Download netinstall iso to local iso directory
debian>$ mkdir iso debian>$ cd ~/iso debian>$ curl -L -O https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.10.0-amd64-netinst.iso or debian>$ curl -L -O https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-11.0.0-amd64-netinst.iso
curl
- -L If the server reports that the requested page has moved to a different location, this option will make curl redo the request on the new place. (redirect)
-O Write output to <file> instead of stdout.
Open TCP Port 9090 if firewall is installed
If you have ufw for your firewall:
debian> $ sudo ufw allow 9090/tcp debian> $ sudo ufw reload
Login to Web Console with browser from your workstation (PC, Mac or Linux)
Add IP address for debian system in your /etc/hosts file so you can type following URL in the browser.
% curl -I http://debian:9090 HTTP/1.1 301 Moved Permanently Content-Type: text/html Location: https://debian:9090/ Content-Length: 73 X-DNS-Prefetch-Control: off Referrer-Policy: no-referrer X-Content-Type-Options: nosniff Cross-Origin-Resource-Policy: same-origin
Chrome or Firefox --> https://debian:9090/ --> Advanced --> Proceed to debian
- Activate default networks in virtual machines to avoid following error
- Also, check on [x] Run when host boots
Creation of VM vm1 failed ERROR Requested operation is not valid: network 'default' is not active Domain installation does not appear to have been successful. If it was, you can restart your domain by running: virsh --connect qemu:///system start vm1 otherwise, please restart your installation.
Create your first virtual machine (vm1) from Web Console
Virtual Machines --> Create VM Name: vm1 Connection: System Installation type: Local install media Installation source: /home/tchung/iso/debian-10.10.0-amd64-netinst.iso Operation system: Debian 10 (buster) Storage: Create new volume Size: 20 GiB Memory: 2 GiB [x] Immediately start VM
Install Debian 10 or 11 on virtual machine as you do in physical machine
https://www.debian.org/releases/stable/amd64/
Login to your first virtual machine (vm1) with ssh and confirm you can ping
Add IP address for vm1 in your /etc/hosts file on debian system so you can ssh to vm1 instead of IP address
debian>$ ssh vm1
vm1>$ ping www.google.com
... works!
Updating osinfo-db for osinfo-query and virt-install
So I was creating vm using virt-install in command line and I had to know --os-variant value.
Unfortunately, existing osinfo-query would not return the distro I needed (ubuntu20 for example).
I discovered that it was not libosinfo-bin but osinfo-db pkg that needed to be updated.
I also discovered updated version of osinfo-db pkg is available from sid.
I could add a repository for sid in /etc/apt/sources.list temporarily so I could install it using apt install command.
- Since the pkg does not have any dependency, I've decided to install the pkg in good old fashioned way.
$ curl -O -L https://deb.debian.org/debian/pool/main/o/osinfo-db/osinfo-db_0.20210215-1_all.deb $ sudo dpkg -i osinfo-db*.deb
Now, I'm able to find the --os-variant value I needed which was missing before.
$ osinfo-query os -f short-id | grep ubuntu20 ubuntu20.04 ubuntu20.10
Does osinfo-db 20210809 detect debian11 ?
So you noticed new version of osinfo-db pkg
- Unfortunately, it still does not detect "debian11" yet.
According to GuidoGünther "...merged already so it should come to Debian soon."
According to PinoToscano "...debian11 was added to upstream osinfo-db few days ago; when there is a new release that contains it, I will upload it to unstable."
In the mean time, continue to use "debian10" for --os-variant value
$ dpkg -s osinfo-db | grep -i version Version: 0.20210809-1 $ osinfo-query os -f short-id | grep debian11 (none)
What about osinfo-db 20210903 from upstream ?
- I just noticed osinfo-db 20210903 from upstream
- Yes, this one can detect "debian11"
However, Debian project has not released official osinfo-db pkg as of today (2021.09.03)
- Can I still use it from upstream? Sure.
How can I import to our existing system? You'll need to install osinfo-db-tools in order to get osinfo-db-import
- So here are the steps to import:
$ curl -L -O https://releases.pagure.org/libosinfo/osinfo-db-20210903.tar.xz $ sudo apt -y install osinfo-db-tools (if you haven't installed) $ sudo osinfo-db-import osinfo-db-20210903.tar.xz
- To check if it can detect "debian11"
$ osinfo-query os -f short-id | grep debian11 debian11
How many VMs am I running?
vm is a custom script based on virsh, virt-install, virt-clone etc.
As of 2021.08.29, I'm running 15 VMs:
$ vm list Id Name State ------------------------ 30 arch21 running 9 c79 running 10 c84 running 13 d09 running 15 d10vm running 35 d11vm running 2 f32 running 12 f34 running 4 lm19 running 5 lm20 running 14 mj21 running 16 mx19 running 33 nl84 running 41 u18vm running 42 u20vm running $ vm list | grep running | wc -l 15
Usage shows less than 3% of total 8 CPUs and less than half of the total 64 GBs of memory.
