Greetings,
I'm working on allowing a session vm to create a tap iface.
the vm has this defintion:
<interface type='ethernet'>
<mac address='52:54:00:a7:79:6b'/>
<target dev='veth0'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x04' slot='0x00'
function='0x0'/>
</interface>
when I try to start the vm, I get this error: Unable to create tap device
veth0: Operation not permitted
searching the code led me to this line:
https://github.com/libvirt/libvirt/blob/0caacf47d7b423db9126660fb0382ed56cd077c1/src/util/virnetdevtap.c#L232
I've looked on line and found out I need the net_admin_cap set. so I took the
relevant code in to a dedicated test file and using pam_cap I've defined such
cap
for the test file, all went well.
so I took it back to virsh and defined that cap to virsh but I'm still getting
the same issue, see: https://ibb.co/zHggRQZ
the os is debian 12
any ideas why I'm still getting this error?
Thanks,
Dagg
