Hello!

ovirt 3.2 -> 3.3 -.3.4 and now 3.4.1 with all 3 nodes acting also as
gluster replicated nodes - you may also run into gluster issues -
compatibility between different gluster version, slit-brain etc.  -
client&server when you apply gluster updates

1. no downtime should happen, as you can upgrade hosts by moving
   them to maintenance, which will live migrate VMs running on them.

2. fedora 18 is EOL, so 'yum update' isn't going to help here.

3. re-install host should refresh vdsm and its dependent packages if

I've followed those steps, and I can get VMs migrated *to* the updated
nodes. I have two worries:

  1. VMs migrated to the updated nodes cannot be migrated back to the
 old nodes. So once I start, it's all-in or nothing. Is that to be
 expected?


on fedora hosts this can happen, since there is no live migration 
compatibility between fedora versions.

on .el6 hosts this shouldn't happen[1]



  2. Once all the nodes are backed up, is there a fairly sure-fire way
 to update the master engine? Is that documented somewhere?


a. you should be able to upgrade engine or hosts regardless of each
   other.
b. the setup (upgrade) script takes a db backup just in case. if you
   happen to run it in a VM, snapshot/backing it up doesn't hurt as
   well.
c. if upgrading to a new minor version, note to change in the upgraded
   engine the cluster and DC level to benefit from new features.




Thanks!

Unfortunately, you are been hit by 
https://bugzilla.redhat.com/show_bug.cgi?id=1078312

It is fixed on gerrit, but you'll need VDSM >= 4.14.8.1

Re: [ovirt-users] gluster performance oVirt 3.4

Underlying FS is XFS
GlusterFS - glusterfs-3.5.0-2.el6
I'm using CentOS, if this is problem could RHEL
packages be used? why CentOS packages are compiled
without native glusterfs support?

1. no downtime should happen, as you can upgrade hosts by moving

2. fedora 18 is EOL, so 'yum update' isn't going to help here.

3. re-install host should refresh vdsm and its dependent packages if

I've followed those steps, and I can get VMs migrated *to* the updated 
nodes. I have two worries:


 1. VMs migrated to the updated nodes cannot be migrated back to the
old nodes. So once I start, it's all-in or nothing. Is that to be
expected?

 2. Once all the nodes are backed up, is there a fairly sure-fire way
to update the master engine? Is that documented somewhere?

Which is the proper way of keeping nodes up to date?

I tried from WebUI, after putting node on mainetnance
"[clear.cache.gif] Host is in maintenance mode, you can Activate it by
pressing the Activate button. If you wish to upgrade or reinstall it
click here ."

but no effect, so I guess that installing ovirt repo and
fedora-ovirt-preview repo is the proper way, right?


I'll add that I'm also interested in a discussion of this question.

I just inherited an oVirt cluster at work that's running 3.2 on Fedora
18 and would dearly love some direction about updating things without a
system-wide downtime.


1. no downtime should happen, as you can upgrade hosts by moving them to 
maintenance, which will live migrate VMs running on them.


2. fedora 18 is EOL, so 'yum update' isn't going to help here.

3. re-install host should refresh vdsm and its dependent packages if the 
repo's configured have newer versions. when the host is in maint, you 
can simply run 'yum update' on the host, then re-activate it (of course 
reboot if kernel got updated, etc.)

Re: [ovirt-users] help with sriov vdsm hook?

Anyone gotten the SRIOV hook to work with Solar Flare 10g cards? Any advice?

I've gotten the hooks installed on my host nodes, and added a string to my engine. The 
card is up in SRIOV "mode" on the host and virtual instances are available. I 
can see the hooks running in the vdsm logs, but can't tell what they are doing from 
there. They are not attaching the sriov card instance to my VM though, so I'm at a loss.


you can compare the generated livirt xml send to qemu by vdsm and 
compare to what you expected to happen by the hook.




As an aside, it'd be really nice to have hooks register with the engine and add 
proper custom strings to the setup. Failing that, some explicit documentation 
on EXACTLY what string should be used for the hook would be nice. My first pass 
at it resulted in an improper string that caused my host to crash/hang and 
reboot when I attempted to start a VM with it the first time.


each hook has a README - maybe send a patch to elaborate more on the one 
not clear enough to you?




Speaking of which, I added my custom string to UserDefinedVMProperties, not 
CustomDeviceProperties. Was that correct?


yes. it was correct.

Hi,


Im very new to virtualization on Linux, wanting to kick the tires
some, and am wondering where best to go next.

Right now, ive done the 'all in one install' of ovirt 3.4 on a single
fedora 19 machine. Its a desktop with a wifi network interface, and im
trying to set up the kvm hypervisor in combination with macvtap. Any
pointers to docs on what best to do next is appreciated. Im currently
trying to make sense of this:
http://www.ovirt.org/Quick_Start_Guide

Also, as far as I can tell, there seems to be an issue with the
detection of my wireless wifi network interface 'wlp2s0' as it doesnt
seem to show up anywhere in the interface. I can attach the
'ovirtmgmt' network to my standard wired ethernet interface 'p2p2',
but that device is not in use on the machine and it is disconnected
from the network.

Reading about linux virt and issues with bridging with wifi NIC's on
the web made me, perhaps incorrectly here, assume that a wifi nic
might be an issue, so thats where the idea to use macvtap came from.

Manual setup of macvtap seems to work, as i can do this without issues
on a root prompt on the same machine:

ip link add link wlp2s0 name macvtap0 type macvtap
ip link set macvtap0 address 1a:46:0b:ca:bc:7b up
ip link show macvtap0

But the wifi interface 'wlp2s0' does not seem to show up in the ovirt
web gui interface.

Im sorry if I sound confusing here, but that may be just because im
really still confused about ovirt.
;)

So any pointers on what to read up on or do next is appreciated,


Thanks,


Regards,


John Smith.

ovirt is meant to manage your datacenter, so not the best match for 
running with a wireless nic i guess.

vdsm may even be filtering it (danken?)

you are not supposed to need the promiscious hook for sniffing/mirroring

Could you explain what you have done, and what do you need promiscuouity
for? oVirt has "port mirroring" that allows to mirror ip traffic from
one vm network to another.

The only real issue is jboss, as the log collector is not actually used and 
should be made completely optional.

The fact that fedora's jboss is incompatible with us should not make us not 
provide users service if they like by downloading and extracting upstream jboss 
to /opt or similar.

I do not see any reason to force users into fedora-19 only because something 
that is easy to workaround.

Fedora 20 is quite different from Fedora 19. I guess that once we'll be able to 
support it as clean install the safest path will be backup / export
from F19; clean F20 install, restore / import into F20.


TBH, maybe we should focus on F21 and skip F20 since its 6 months since

Hi,
You probably have a more detailed event at the event log within the user 
interface, please try to deploy host again, go to the right lower tab and 
follow the progress.
If you send the 
/var/log/ovirt-engine/host-deploy/ovirt-20140510123905-domain.com-3fd2d93.log I 
will be able to see what went wrong.

[ovirt-users] Allinone One NIC for multiple network

[Kevin Tibi]

Hi,

i have a little problem with my ovirt allinone. I have a dedibox with one
NIC. I can't use VLAN tagging on this network. I need to create a second
network for specific VMs. So, i can't add this network on my physical NIC
because i have already the mgnt network.

Can i create a tap/virtual NIC for this network ? Ovirt see tap interface
in interface's host?

Thx.

Kevin.

Based on above errors, I think that for some reason these two python
related packages that were updated yesterday are causing some problems with
vdsm.
Can you confirm that you can run ok the 3.4 vdsm with those?

vdsm-4.14.6-0.fc19.x86_64

May 10 21:24:23 Updated: python-ethtool-0.9-2.fc19.x86_64
May 10 21:24:23 Updated: python-lxml-3.3.5-1.fc19.x86_64

I can also try to rollback and see...

I didn't change anything on this server.
It is an all-in-one config so both engine and vdsm host are on it.
Yesterday and every previous day I was able to start the system and start
the VM; I only applied the yum update command yeseterday
(with --exclude=sos due to the opened bug) and then I made shutdown of the
system.
Today after startup I got this problem.

[root@tekkaman vdsm]# vdsClient -s 0 getVdsCaps

it seems the error in vdsm.log when I run the command above is of this type:

HI!

Created 2 node setup with oVirt 3.4 and CentOS 6.5, for storage created

/rhev/data-center/mnt/glusterSD/127.0.0.1:_gluster01 type fuse.glusterfs
(rw,default_permissions,allow_other,max_read=131072)

when i making gluster test with dd, something like
dd if=/dev/zero bs=1M count=2
of=/rhev/data-center/mnt/glusterSD/127.0.0.1\:_gluster01/kaka
i'm gettting speed ~ 110 MB/s, so this is 1Gbps speed of ethernet adapter

but with in VM created in oVirt speed is lower than 20 MB/s

why there is so huge difference?
how can improve VMs disks speed?



What are your gluster volume settings? Have you applied the following 
performance tunables in gluster's virt profile:


eager-lock=enable
remote-dio=enable

[ovirt-users] AIO 3.4 on fedora 19 initial errors before coming up

[Gianluca Cecchi]

Hello,
I have an environment with All-In-One on Fedora 19.
Packages version is aligned with oVirt repos up to 3.4.0-1.fc19

I start and shutdown the system every day as it is a personal computer.
Storage is composed by two local storage domains.

Every time system boots it takes about 7 minutes to have datacenter up.
The system has 16Gb of ram and internal disk is an ssd one (one of the
storage domains is on a sata disk).
I see some errors for some minutes before the DC and storage domains come
up.
I would like to know if this is expected or if I have some correctable
problems as the system comes form several updates up to the current 3.4.0
version.
Here you can find relevant logs with latest lines during yesterday shutdown
and today lines up to DC  has been activated.

Thanks in advance,
Gianluca
