Created attachment 451923 [details] emerge --info libvirt g50-80 ~ # virsh list ^C it hangs until I manually terminate the process attached is the emerge --info
Sounds like a genuine libvirt bug. Can you please attach debugger and run 't a a bt' and attach the output here? Also - what's the connection URI you're using? qemu:///system I presume - in which case it would be helpful to have the same debugger output for the libvirtd process as well.
unfortunately I have reinstalled linux, the problematic virsh is no longer there
