Install virt manager in LFS

tosaikiran · 02-05-2022, 03:41 AM

Hi,

I have completed LFS-11.0. I have installed qemu, from BLFS. I would like to know how to install virt manager in LFS, so that I can have a GUI to create VMs. I have looked at several posts on the internet. But I am not able to find a solution for that. Could someone help me out here.

Thanks in advance for your time and help.

Regards,
Sai Kiran.

qemu is only an emulation layer, you need to install KVM to use libvirt and you have to have the kernel extension modules running for it to work.

Did you build your own kernel, and if you did, did you enable KVM ?

This has nothing to do with the OP the OP is asking about a GUI to manage virtual machines NOT infor on qemu etc, please take the time to read the posts properly before replying.

Try this:

I did read it, and without the first step of having libvirt already installed and working, installing virt-manger would do nothing..

The dependencies listed at slackbuilds.org may help in what is required.

Hi,

Thanks for your help. I looked at the dependencies and I am right now building all those dependencies from source on LFS. It will take time as there are other dependencies for libvirt dependencies. I will install them all and hopefully I will be able to install virt manager. I will update the same here.

Hi Keith,

I have installed the dependencies for virt manager in my LFS system. So far so good. But I get the following error, when I start the virt-manager. "Namespace GTK not available". GTK is present in the system. One of the forums online suggested to install gir-gtk software. I have tried to find the source code for it but I am not able to find it. Could you please let me know if that's the packaage needed to fix the error? If yes, could you point me to the source code.

Thanks,
Sai Kiran.

Hi,

Thanks Keith.

I have installed it. But it is in /usr/lib folder. But the python script is looking for it in /usr/lib64 folder. I am able to get around that issue. virt-manager is coming up . I see the GUI. But it says that I need to install libvirtd service. Do I have to compile libvirtd service or is it part of some other software?

Thanks,
Sai Kiran.

that sound like a systemd thing, sorry can't help you there, if you are using systemd have you compiled virt-manager for systemd some apps need slightly different compile options.

as for the folder thing just check that /etc/ld.so.config includes both /usr/lib and /usr/lib64 ( i personally sym link /lib and /usr/lib to /lib64 and /usr/lib64 respectavly )
