One of the first tasks you will want to do is to verify that the drivers have actually been loaded into your system.
After the para-virtualized drivers have been installed and the guest has been rebooted you can verify that the drivers have loaded. First you should confirm the drivers have logged their loading into
/var/log/messages
# grep -E "vif|vbd|xen" /var/log/messages
xen_mem: Initialising balloon driver
vif vif-0: 2 parsing device/vif/0/mac
vbd vbd-768: 19 xlvbd_add at /local/domain/0/backend/vbd/21/76
vbd vbd-768: 19 xlvbd_add at /local/domain/0/backend/vbd/21/76
xen-vbd: registered block device major 202
You can also use the
lsmod
command to list the loaded para-virtualized drivers. It should output a list containing the
xen_vnif
,
xen_vbd
,
xen_platform_pci
and
xen_balloon
modules.
# lsmod|grep xen
xen_vbd 19168 1
xen_vnif 28416 0
xen_balloon 15256 1 xen_vnif
xen_platform_pci 98520 3 xen_vbd,xen_vnif,xen_balloon,[permanent]
