Dedicated Virtual Server Mirohost Cloud

Mirohost Cloud

The Mirohost cloud infrastructure allows you to deploy servers for any task in a matter of seconds. You can choose from four product lines optimized for specific business or development needs.

Which cloud server lines are available, and what are they suitable for?

GO — Lightweight solutions for an instant start. Ideal for testing, learning, sandboxes, or launching small pet projects.

FLEX — A cloud for growing businesses. Balanced in power and cost, these servers are designed for corporate websites, CRM systems, and applications in the active phase of development.

PLUS — For DevOps and team development. Powerful configurations for testing, staging, or production environments where high memory and disk resources are required.

POWER — Performance without compromises. Robust solutions for businesses operating under heavy loads. They guarantee the stable operation of infrastructure, large databases, and high-load systems even during peak hours.

We offer two virtualization systems:

Shared vCPU (Intel and AMD): Virtual processors are shared with other virtual machines on the node. The AMD option offers a larger amount of fast SSD storage with the same number of cores and RAM.

Dedicated vCPU (Intel and AMD): Resources (CPU and RAM) are fully reserved and allocated specifically to your server for maximum stability. Here, the AMD solution also offers a higher capacity drive.

We use official operating system builds for cloud platforms (general purpose images) that include the cloud-init system. Images are updated weekly. During installation, you can specify your own SSH key or use an automatically generated one. The root password is sent to the contact email address specified during the registration of your hosting package at the exact moment the virtual machine is launched.

Cloud Dashboard Overview

To start working with a cloud server, you need to install an operating system. This can be done using various methods:

1. Automatic Installation - to install the operating system, simply select an image from the list, specify the server name, and click "Confirm and Install".

You can choose one of the following operating systems from the list:

• Alma-Linux
• Centos-Stream
• Debian
• Fedora
• Freebsd
• Opensuse
• Oracle Linux
• Rocky Linux
• Ubuntu
• Microsoft Windows Server Eval As well as:
• Openclaw
• Wireguard-Server

Please note! OS activation keys are not provided by Mirohost.

Activation is required for the proper functioning of Microsoft Windows Server after the Evaluation period expires.

2. Manual Installation - deploy a clean cloud server, mount your own ISO image, and start the installation. You can manage the OS installation process via the built-in VNC console in the control panel.

3. Installation from a Backup - you can pre-configure server backups, and if an operating system failure occurs at any point, you can reinstall the OS on the server using a previously prepared backup.

4. Server Cloning - the ability to deploy a new server in one click, which will be a complete copy of an already configured and running server in your profile.

Frequently Asked Questions

I don't remember the root password. What should I do?

We do not store passwords for the virtual machines (VMs) under your management. The administrator password is sent to your email only once, at the moment the VM is created. If the password has been changed since then and you have forgotten it, we recommend using the password reset feature via the control panel: go to the "Recovery" section – "Root Password".

Are there any incoming/outgoing traffic speed limits?

Currently, for all tariff plans, the incoming and outgoing traffic speed is set at 1Gbps.

What happens if the traffic limit is reached?

The outgoing traffic limit is implemented to prevent network abuse. In cases of systematic overuses, traffic may be limited individually depending on the specific situation.

Can I migrate from eVPS to Cloud?

The eVPS solution is designed for website hosting and comes with a built-in panel for managing web services. Conversely, the Cloud server panel manages the virtual machine as a "black box," without having access to its internal configurations or files. Data migration when moving from eVPS to Cloud is performed entirely on the user's side. Please note that cloud tariffs require independent system administration, development, and technical support of the project by the client.

How can I change my tariff plan?

Upgrading to a higher tariff: performed automatically. In the control panel, open the "Resize" section and click "Select" next to the desired package. Changes to the configuration and the price recalculation will occur instantly.

Downgrading to a lower tariff: technically impossible for an already created server. To reduce costs, order a new (smaller) server, migrate your data manually, and delete the old server. The remaining balance from the old server will be credited back to your billing account.

How do I change the rDNS?

Changes can be made through the "Networks" section in the hosting control panel.

Can I switch from Shared to Dedicated tariffs and vice versa?

Yes, this is possible. However, changing the tariff is only permitted to a plan with a larger disk space.

What is the Rescue Recovery System?

List of available recovery images:

• Debian-Live
• Finnix
• Rescuezilla
• Systemrescue
• WinPE

Short description of the images and their purpose: Debian-Live A full-featured Linux environment (Debian) that runs entirely in the server's RAM without installing onto the drive. It is ideal for manually mounting file systems, copying data, editing configuration files (e.g., /etc/fstab or network settings), and resetting passwords in a familiar Linux environment.

Finnix A small, extremely fast, and optimized Live Linux distribution for system administrators that lacks a graphical interface (CLI only). It includes a comprehensive set of utilities for network testing, RAM checks, bootloader (GRUB) repair, and low-level disk operations.

Rescuezilla A specialized tool known as the "Swiss Army knife" of backup and recovery. It features a simple graphical user interface and is designed for deploying or creating full disk images (clones) and individual partitions. It helps quickly restore a server from a backup even if the main OS is completely corrupted.

Systemrescue (SystemRescueCd) One of the most popular tools for emergency Linux system recovery. It contains a large number of administrative utilities for disk partitioning (GParted, fdisk), recovering deleted files (TestDisk, PhotoRec), checking file system integrity (e2fsck), and fixing boot errors.

WinPE (Windows Preinstallation Environment) A lightweight version of the Windows operating system that boots from a virtual drive. It is indispensable if your cloud server runs on Windows Server or Windows 10. It allows you to check disks using the chkdsk utility, edit the registry (regedit) of a crashed system, replace system drivers, or copy critical corporate data to external storage.

Use the VNC console to perform recovery tasks in Rescue mode. Once the work is complete, click the "Unrescue" button in the management dashboard; the Rescue disk will be detached from the server, and the system will boot normally.

Can I use my own images for virtual machines?

If the required OS image is missing from the provided selection, please submit a ticket to our technical support team so we can consult with you on an individual basis.

Can I manage the VNC console using mobile devices and tablets?

We do not recommend this, as working from a mobile device involves limited input controls due to screen size limitations. Mobile browsers do not interpret the VNC console window as a text input field, preventing the on-screen keyboard from appearing when the focus is inside the VNC console. The only way to type into the VNC console in such a scenario is to switch to another window on your mobile device, enter the text there, copy it to the clipboard, and paste it into the VNC console using the panel's "Paste Clipboard" button. Tapping with a finger usually works correctly if a graphical terminal is used. Additionally, certain browsers like Safari may block the opening of a new window when a VNC session is initialized.

Can I migrate my server from one data center to another (between Ukraine and Poland)?

Yes, this is possible. Create a new order in the other data center with an identical or higher tariff plan, and during the creation of the new machine, choose the "Clone Server" option. The system will prompt you to select which server you want to clone. After the cloning operation is complete, a server will be created in the target data center as an exact copy of the selected server, but with a different IP address. The migration process between data centers takes time, so you will need to wait for it to finish. Later, you can delete the old server or build a cluster across both data centers.

There are many "Server stopped" or "Error" logs in the server history

The most likely cause of this error is that you created the virtual machine from a desktop operating system ISO image. Desktop operating systems like Windows 10/11 have power-saving features enabled by default; therefore, during periods of inactivity, they put the virtual machine into sleep or hibernation from within. When interacting with the KVM hypervisor, this can lead to errors because the hypervisor cannot properly suspend or communicate with the VM. We recommend disabling sleep and hibernation modes within the OS settings, or simply stopping the virtual machine when it is not in use.

The Windows server/machine sometimes hangs while being stopped/rebooted via the server management dashboard. What should I do?

Windows servers can take a significant amount of time to stop all active services. A standard server shutdown operation via the dashboard waits 3 to 15 minutes, attempting to stop it gracefully. After this period, a forced shutdown process begins to prevent unpredicted consequences. For Windows servers, we highly recommend triggering the "Restart" or "Shut down" operations from directly within the OS itself. These actions are fully managed by the server's internal operating system. Furthermore, shutting down the server via the internal OS will correctly update its status to "Stopped" in the dashboard. The same approach can be applied to Linux servers using Reboot or Shutdown commands, although Linux servers generally do not experience the aforementioned hanging issues.

Is it possible to attach additional disks to my server?

Yes, this is possible by ordering an additional disk. In the "Cloud" section, select "Disks" and click "Order Disk".

A disk of the specified size will be attached to the virtual server using iSCSI technology. A new block device will appear in your server's device list, typically named /dev/sdb (/dev/sdc if another disk is added). You will need to create partitions, format them, and mount them to the file system yourself. Alternatively, when creating a new disk, you can opt to have it pre-formatted with your choice of file system (ext4/xfs/btrfs/ntfs); in that case, you only need to execute the following commands:

mkdir -p /storage

mount /dev/sdb1 /storage

The pre-formatting option is available only for disks up to 512GB in size.
