Hi,
I am trying to define a container using libvirt, and I need to allow access of the device /dev/uio0 on the host on the container as well. That is, I have the following line in the container config file:
lxc.mount.entry = /dev/uio0 dev/uio0 none bind,create=file
lxc.cgroup.devices.allow = c 249:1 rwm
And I want to add the above via the libvirt XML file for the container.
I tried something like:
<filesystem accessmode="passthrough" type="mount">
<source file="/dev/uio0" />
<target dir="/dev/uio0" />
</filesystem>
But it gave me error:
root# virsh -c lxc:/// define lxc_v.xml
error: Failed to define domain from lxc_v.xml
error: missing source information for device /dev/uio0
Can someone pls help, how I can add the /dev/uio0 to the xml file?
Thanks
Anjali
