hi,
i am trying to create hvm in xen via libvirt but i am facing some error. i
installed the packages like bltap-utils, blktap-dkms in my dom0.
virsh create tiny_core.xml
p11-kit: invalid config filename, will be ignored in the future:
/etc/pkcs11/modules/gnome-keyring-module
error: Failed to create domain from tiny_core.xml
