Hi,
I think that issue is due to the fact that my Guest is a transient domain.
When shutting down it or migrating to another host , then virsh list --all doesn't
show this Guest anymore.
How may I make this Guest a persistent one ?
( i.e. this Guest has been created via RHEV-M GUI)
Thx for hlep.
Regards,
J.P.

I have some questions regarding the way that networking is handled via qemu/kvm+libvirt --
my apologies in advance if this is not the proper mailing list for such a question.
I am trying to determine how exactly I can manipulate traffic from a?_guest's_ NIC
using iptables on the _host_. On the host, there is a bridged virtual NIC that
corresponds to the guest's NIC. That interface does not have an IP setup on it on the
host, however within the vm itself the IP is configured and everything works as expected.
During my testing, I've seemingly determined that traffic from the vm does NOT
traverse iptables on the host, but I _can_ in fact see the traffic via tcpdump on the
host. This seems odd to me, unless the traffic is passed on during interaction with the
kernel, and thus never actually reaches iptables. I've gone as far as trying to log
via iptables any and all traffic traversing the guest's interface on the host, but to
no avail (iptables does not see any traffic from the guest's NIC on the host).
Is this the way it's supposed to work? And if so, is there any way I can do IP/port
redirection silently on the _host_?
Thanks in advance for any insight that anyone can share :)

Hi,
I'm facing following issue ( or misunderstanding from my side)
I try to attach a device to a running guest ; I want to do it persistently and without
having to restart the GUEST .
By using options "-live - persistent" , I got following error :
[root@ldc01omv01 data]# virsh attach-device VM_RHEL7-1
"../data/channel_omnivision_to_be_used.xml" --live --persistent
Please enter your authentication name: root@ldc01omv01
Please enter your password:
error: Failed to attach device from ../data/channel_omnivision_to_be_used.xml
error: Requested operation is not valid: cannot modify device on transient domain
[root@ldc01omv01 data]# virsh -r list --all
Id Name State
----------------------------------------------------
8 VM_RHEL7-2 running
11 W2008R2-2 running
12 VM_RHEL7-1 running
By using options "-live " , I got following error :
[root@ldc01omv01 data]# virsh attach-device VM_RHEL7-1
"../data/channel_omnivision_to_be_used.xml" --live
Please enter your authentication name: root@ldc01omv01
Please enter your password:
error: Failed to attach device from ../data/channel_omnivision_to_be_used.xml
error: Unable to read from monitor: Connection reset by peer
[root@ldc01omv01 data]# virsh -r list --all
Id Name State
----------------------------------------------------
8 VM_RHEL7-2 running
11 W2008R2-2 running
[root@ldc01omv01 data]#
And then the Guest is powered off !!
If I try to attach device when the Guest is off , then :
[root@ldc01omv01 data]# virsh attach-device VM_RHEL7-1
"../data/channel_omnivision_to_be_used_1.xml" --config --persistent
Please enter your authentication name: root@ldc01omv01
Please enter your password:
error: failed to get domain 'VM_RHEL7-1'
error: Domain not found: no domain with matching name 'VM_RHEL7-1'
FYI , xml file contents is :
<channel type='unix'>
<source mode='bind'
path='//var/lib/libvirt/qemu/VM_RHEL7-1_omnivision_1.agent'/>
<target type='virtio' name='omnivision_1.agent'/>
</channel>
I'm using libvirt-1.2.17-13.el7.x86_64
Any help is welcome.
Thanks.
