Dear autotest team,
After running some very simple install and uptime tests I kept getting the
following information which later breaks my VM networking:
13:29:00 INFO | [qemu output] qemu-kvm: -netdev tap,id=idKvL0U5,fd=22:
TUNGETIFF ioctl() failed: Inappropriate ioctl for device
13:29:00 INFO | [qemu output] TUNSETOFFLOAD ioctl() failed: Bad address
The qemu command that is generated is the following:
13:29:00 INFO | Running qemu command:

I investigated the error and it is fixed if I do the following code
intervention:
--- a/client/virt/kvm_vm.py
+++ b/client/virt/kvm_vm.py
@@ -1406,7 +1406,7 @@ class VM(virt_vm.BaseVM):

if nic.nettype == 'bridge' or nic.nettype == 'network':
- if not nic.get('tapfd'):
+ if True: #not nic.get('tapfd'):
nic.tapfd = str(virt_utils.open_tap("/dev/net/tun",
nic.ifname,
vnet_hdr=False))
I have the newest autotest version which contains a patch solving similar nic
problems. Perhaps something is missed by the patch.
I am glad to hear if there are any ideas about this issue.
Kind regards,
Plamen
