Hello Guix! I need help with over-coming this issue (http://debbugs.gnu.org/cgi/bug report.cgi?bug=36634). The issue can be with libvirt or virt-manager or both.
The error mentioned in that bug thread was copy pasted directly from virt-manager error dialog. Screenshot of the same can be obtained at ht tps://upload.disroot.org/r/b9EFgmac#66RuSoRjxbaK0Py7zmy862DgSI376p8fn9t HukGxgAo=. Efraim Flashner tried to reproduce the error but resulted in negative outcome. For Efraim, the libvirt was trying to read '/sys/fs/cgroup/unified/cgroup.controllers' and worked; whereas for me, the libvirt was trying to read '/sys/fs/cgroup/unified/machine/cgroup.controllers' and led to error. The directories are different. The confusion is why? Thank you! Regards, RG.
