[Solved] libvirtd (qemu) cannot start guests

Message

lyallp · Post by **lyallp** » Mon Jan 12, 2026 6:51 am

I seem to be having problems using Virtual Machine Manager to start my VM's.

I tried reinstalling qemu, stopping and restarting the daemons, appropriately.

The error is that it can't find a kernel module but I even rebuilt the kernel and rebooted

Suggestions welcomed.

My kernel modules include kvm (or more specifically, kvm_intel, as I have an Intel CPU)

Presuming you've already familiarized yourself with https://wiki.gentoo.org/wiki/Kernel/Upgrade, so I'll skip repeating those items.

Check for qemu/kvm account/groups and if your user is a part of them.
Check if /dev/kvm exists and if you have permissions to execute (ls -l) same.
Check for cpu virtualization support: grep -E "vmx|svm" /proc/cpuinfo
Check your bios and make sure related functions are enabled for virtualization support.
Check dmesg | grep -E "qemu|kvm" for output and any additional hints.
Retry same after unloading and reloading the module.
Rebuild qemu.

What did confuse me was I had booted and closed down another VM only a couple of minutes earlier.

Somewhere along the line, user qemu lost group kvm.

(kvm was required to access /dev/kvm, at least on my system it is)

I only recently did a complete system rebuild using --emptytree @system @world, as in a couple of days earlier.
