QEMU virtualization

Available Images for QEMU Virtual Machines

Here are some of the available system parameters for your reference:

• debian10, debian11, debian12, debian13
• ubuntu18, ubuntu20, ubuntu22
• centos8, centos9 (actually deployed as Stream versions)
• alpine3.15, alpine3.16, alpine3.17, alpine3.18
• openwrt21, openwrt22, fedora37, fedora38, fedora39
• rockylinux8, rockylinux9, oracle8, oracle9
• oracle7, centos7 (all require enabling CGroupV1 in GRUB, otherwise they won't start - see FAQ for details)
• kali, archlinux

• Note that all are combinations of lowercase letters + numbers or lowercase letters only. Try them yourself - if the system is not found in the search, the script will automatically exit.
• Version numbers can include English decimal points to accommodate Alpine version numbers.
• Systems that fail to start may be due to insufficient disk space, memory, or incompatibility with the host machine. Check the error messages for systems that won't start.
• Currently, only self-compiled images are used for virtual machine systems. Non-self-compiled images lack dependencies and configurations and cannot be used.

Download Script

International:

curl -L https://raw.githubusercontent.com/oneclickvirt/lxd/main/scripts/buildvm.sh -o buildvm.sh && chmod +x buildvm.sh && dos2unix buildvm.sh

Domestic (China):

curl -L https://cdn.spiritlhl.net/https://raw.githubusercontent.com/oneclickvirt/lxd/main/scripts/buildvm.sh -o buildvm.sh && chmod +x buildvm.sh && dos2unix buildvm.sh

Usage

./buildvm.sh ServerName CPUCores MemorySize DiskSize SSHPort ExternalStartPort ExternalEndPort DownloadSpeed UploadSpeed EnableIPV6(Y or N) System(leave empty for debian11)

CPU cores must be less than or equal to the host machine's cores. Memory size is calculated in MB, disk size in GB, download and upload speeds in Mbit. EnableIPV6 doesn't necessarily need to be Y or N - it can be omitted, defaulting to disabled IPV6.

If both ExternalStartPort and ExternalEndPort are set to 0, no external port range mapping will be performed - only the basic SSH port will be mapped. Note that these cannot be empty - set them to 0 if no mapping is needed.

Supports custom server systems. When left empty, debian13 is used by default. Note that the parameter should be system name + version number.

Except for Alpine systems, all other systems require disk size greater than 6G, otherwise the system won't start, cannot initialize and function, and will crash during the setup process.

Example

Here's the information for the example server being created:

Property	Value
Server Name	test
SSH Login Username	root
SSH Login Password	Randomly generated
CPU Cores	1
Memory Size	256MB
Disk Size	10G
Internal/External Port Mapping Range	20002 to 20025
Upload Bandwidth	500Mbit
Download Bandwidth	500Mbit
Auto-configure External IPV6	N
System	debian13

./buildvm.sh test 1 512 10 20001 20002 20025 500 500 N debian13

To enter the virtual machine, execute:

lxc console test

To exit, first press and hold Ctrl then press a, release them, then press q.

To view information, execute:

cat ServerName

For example, to query the example's information:

cat test

Delete Test Server

lxc stop -f test
lxc delete -f test
rm -rf test
rm -rf test_v6
ls
