3.6 upgrade issue
by Jon Archer
Hi all,
Wonder if anyone can shed any light on an error i'm seeing while running
engine-setup.
If just upgraded the packages to the latest 3.6 ones today (from 3.5),
run engine-setup, answered the questions, confirming install then get
presented with:
[ INFO ] Cleaning async tasks and compensations

Any ideas, where to look to fix things?

MAC spoofing for specific VMs
by Christopher Young
I'm working on some load-balancing solutions and they appear to require MAC
spoofing. I did some searching and reading and as I understand it, you can
disable the MAC spoofing protection through a few methods.
I was wondering about the best manner to enable this for the VMs that
require it and not across the board (if that is even possible). I'd like
to just allow my load-balancer VMs to do what they need to, but keep the
others untouched as a security mechanism.
If anyone has any advice on the best method to handle this scenario, I
would greatly appreciate it. It seems that this might turn into some type
of feature request, though I'm not sure if this is something that has to be
done at the Linux bridge level, the port level, or the VM level. Any
explanations into that would also help in my education.
Thanks,
Chris

python floppy in RunOnce mode
by Giulio Casella
Hi,
I'm trying to boot a vm with non persistent floppy using python ovirt
sdk (the "RunOnce" way in administrator portal), but guest OS can't see
floppy drive. The ultimate goal is to deploy floppy with sysprep
unattend.xml file for windows 7 pools of vm.
Here is a snippet of code I use:
-------------------------------------------------
myvm = api.vms.get(name="vmname")
content="This is file content!"
f=params.File(name="foobar.txt",content=content)
fs=params.Files()
fs.add_file(f)
payload=params.Payload()
payload.set_type("floppy")
payload.set_files(fs)
payloads=params.Payloads()
payloads.add_payload(payload)
thevm=params.VM()
thevm.set_payloads(payloads)
action=params.Action(vm=thevm)
myvm.start(action=action)
xml = ParseHelper.toXml(action)
print xml
-------------------------------------------------
As you can see, for debugging purpose, I print my xml action, and I get:
-------------------------------------------------
<action>
<vm>
<payloads>
<payload type="floppy">
<files>
<file>
<name>foobar.txt</name>
<content>This is file content</content>
</file>
</files>
</payload>
</payloads>
</vm>
</action>
-------------------------------------------------
in the admin portal I can see my vm in "RunOnce" state, but no floppy is
present...
In fact in the vm process command line
(ps -ef | grep qemu-kvm | grep vmname) I can't see -drive option
referring to floppy (I only see 2 "-drive" options, referring to vm
system disk and to a correctly mounted cdrom ISO)
What I'm doing wrong?
(The engine is RHEV-M version 3.4.1-0.31.el6ev)
Thanks in advance,
Giulio

OK, I see a couple of problems.
First off, I didn't have my deploying-host hostname in the hosts map for my engine.
After adding it to /etc/hosts (both hostname and FQDN), when I try to ssh from root@engine to root@host it is prompting me for a password.
On my engine, ~root/.ssh does not contain any keys.
On my host, ~root/.ssh has authorized_keys, and in it there is a key with the comment "ovirt-engine".
It's possible that I inadvertently removed ~root/.ssh on engine while I was preparing the engine (I started to set up my own no-password logins and then thought better and cleaned up, not realizing that some prior setup affecting that directory had occurred). That would explain the second issue.
How/when does the key for root@engine get populated to the host's ~root/.ssh/authenticated_keys during setup?

Issue with kernel 2.6.32-573.3.1.el6.x86_64?
by Michael Kleinpaste
So I patched my vhosts and updated the kernel
to 2.6.32-573.3.1.el6.x86_64. Afterwards the networking became unstable
for my vyatta firewall vm. Lots of packet loss and out of order packets
(based on my tshark at the time).
Has anybody else experienced this?

Performance metric similar to what VMware calls "CPU Ready" would be very u=
seful if it was available in the VM details in the admin portal.=20
It would provide great visibility on VM's performance in an environment wit=

Re: [ovirt-users] [RFI] oVirt 3.6 Planning
by Juan Pablo Lorier
+1 to iso upload from gui
+1 to ceph support (if the way is via Cynder, then integrate Cynder in
Ovirt as you did with neutron to get arround the lack of features in
networking)
I've been asking for several things (with their respective RFEs) and as
versions go by without success, I'm asking again:
- 1049994 [RFE] Allow choosing network interface for gluster domain
traffic
- 1049476 [RFE] Mix untagged and tagged Logical Networks on the same NIC
- 1029489 [RFE] Export not exporting direct lun disk
- 1051002 [RFE] ISO domain should be a simple NFS share containing ISOs

Backup storage domain for the meta data ONLY?
by Nicolas Ecarnot
Hi,
In a lab, I have an oVirt test datacenter using a very old SAN (iSCSI
setup).
There are very few VM on it, and none of them are in critical.
Some risky maintenance is to be planned on the SAN, and the risk is to
lose it all.
To be honnest, to lose these VMs is bearable, but to lose the setup
would be painful (quite long to set everything back up).
This is not an hosted setup, so I guess most of the config lies in the
manager, and this part will stay untouched.
My question : Is there any benefit to add an small additionnal temporary
storage domain where (some unknown by me) meta datas could be duplicated
(knowing that I have not enough room to export the VM)?
What additionnal setup would be saved this way?
