Unable to start libvirt systemd service

[Sharath Kurudi <kurudisharath@xxxxxxxxx>]

Hi all,

    I am using the libvirt 4.9  version. I get the following error when I try to run the command virsh list after the system comes up

virsh list
error: failed to connect to the hypervisor
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory

When I run the command ps -ef | grep libvirtd, to find whether the libvirtd process is running. I get the following message.

 ps -ef | grep libvirtd
root       418     1  0 06:33 ?        00:00:00 /usr/sbin/libvirtd --daemon --config /etc/libvirt/libvirtd.conf
root       420     1  0 06:33 ?        00:00:00 /usr/sbin/libvirtd --daemon --config /etc/libvirt/libvirtd.conf

After sometime, I see that the virsh list command goes through and the command ps -ef | grep libvirtd, gives the following putput

ps -ef | grep libvirtd
root       420     1  0 06:33 ?        00:00:00 /usr/sbin/libvirtd --daemon --config /etc/libvirt/libvirtd.conf

It is found that the libvirt systemd service times out, and for some unkonwn reason the previous libvitrd process is not killed.

I dont see any errors in /var/log/messages or /var/log/syslog.

Could anyone please help?

Thanks

Sharath
