What is the error that you're getting? 
What do you mean by broken snapshot? How did it happen? 
Can you please attach some logs?

Re: [Users] Error on Setting up VLAN

2014-01-01 Thread Assaf Muller 
Looks like bridge public_10 still has vNICs connected to it.

What is the output for:
brctl show public_10

If you select the host and enter the Setup Networks dialog, does the physical 
NIC
have a network on it? If so, remove it (I know you said you did this but it 
looks like
that operation somehow silently failed). After removing all networks on the 
host,
the public_10 bridge shouldn't exist. Also, virsh net-list shouldn't list the 
public_10 network.

If setupNetworks shows a blank NIC, but the public_10 bridge or libvirt 
networks exist, try:
Removing /etc/sysconfig/network-scripts/ifcfg-public_10
Type virsh , then:
virsh net-undefine public_10
virsh net-destroy public_10
Login details:
vdsm@ovirt
shibboleth

After the ifcfg file and libvirt networks are removed, go back to the GUI and 
select 'Save network config',
then restart the host.

At this point the host should come up - No ifcfg file for the network, no 
libvirt network, no bridge.
The setup networks dialog in the GUI should show no network on the physical NIC.
Now make sure (again) that the public_10 network is a VLAN network, and attach 
public_10 to the NIC.
That operation should succeed.

Subject: [Users] Error on Setting up VLAN

Hi everyone and happy new year first !

I'm setting up a test host using VLAN

It holds 2 VM's so I

- Stopped the two VMs and removed the "public_10" network from the NIC
- edited the "public_10" network, checked "enable VLAN tagging" and set 
10 as VLAN identifier
- assigned the "new" edited network to the VMs NIC
- edited the HOST network, clicked the pencil on the relevant NIC and 
clicked "sync network" since it showed the network as "not synced"

Ovirt tried to setup the network but ended with "cannot up interface" 
error and I lost contact with the node

Ovirt is 3.3.2 on Fedora 19 (it is AIO)

Doh.  How did I miss that?

But I see in the disks maintab a disk I deleted several weeks ago. It's 
gone from the physical storage but still shows up here.  Wonder why that 
is?

I've tried updating disk's description with latest bits and it seems to work 
fine..
Can you please attach the relevant engine logs for further investigation.



Did you check the .meta file on physical storage?  It seems to be 
getting updated in the GUI, but not getting written out to the .meta

same issue when I update the Description field.

Thanks a lot for the reply, Shahar.

I wrote a hook based on the floppy hook first, but it didn't work with oVirt 
3.2 and changed the script then to REST-API calls.
I'll test my old Python script, which does manipulate the DOM XML again against 
oVirt 3.3.


Thanks,
René

I'm far from being a programmer, but as I went to compare build
environments, between
qemu-kvm-rhev-0.12.1.2-2.415.el6_5.3.src.rpm
and
qemu-kvm-0.12.1.2-2.415.el6_5.3.src.rpm

and apart other probably not trivial implications, such as guest agent
part, I see that the "configure" command takes one extra argument in
base RH EL 6.5, that is

--disable-rhev-features

The only patch file containing this keyword is

kvm-Block-streaming-disable-for-RHEL.patch

and inside it there are these lines that impacts configure options and

I don't think the rhev argument has instead implications in upstream
source qemu-kvm-0.12.1.2.tar.gz
So I think that if you want to dig more and if you have more
competences, you have to see the full spec file and the full patch
above.
