Anyone using gluster storage domain with WAN geo-rep?
by Steve Dainard
I'm currently using a two node combined virt/storage setup with Ovirt 3.3.4
and Gluster 3.4.2 (replica 2, glusterfs storage domain). I'll call this
pair PROD.
I'm then geo-replicating to another gluster replica pair on the local net,
btrfs underlying storage, and volume snapshots so I can recover my storage
domain from different points in time if necessary. Its also local so
restore time is much better than off-site. I'll call this pair BACKUP.
I'm planning on setting up geo-replication from BACKUP to an EC2 gluster
target. I'll call this host EC2HOST.
PROD ---geo-rep-lan---> BACKUP ---geo-rep-wan---> EC2HOST
I'd like to avoid saturating my WAN link during office hours. I have some
ideas (or combination of):
1. limit bandwidth during certain hours to the offsite hosts. But
realistically the bandwidth I would allocate is so low I don't see the
purpose of this. Also with 8 guests running, I'm noticing quite a bit of
data transfer to the local backup nodes (avg 6-8MB/s), and I'm thinking
there is a lot of thrashing going on which isn't useful to backup offsite
anyways.
2. stop WAN geo-replication during office hours, and restart for
overnight/weekend hours.
3. Not use geo-rep between BACKUP ---> EC2HOST, use rsync on one of the
btrfs volume snapshots so we avoid the thrashing. In this case I could
limit WAN speed to 1MB/s which should be fine for most differences
throughout the day.
So my question is, how do you off-site your storage domains, what
constraints have you identified and how have you dealt with them? And of
course how would you deal with the scenario I've oulined above?
Thanks,
*Steve*

difference between thin/depentend and clone/dependent vm virtual machine
by Tamer Lima
Hello,
I created VMs by two ways :
1) on tab virtual machines > new vm > template (centos_65_64bits)
1.1 configuration : I do not select stateless checkbox
1.2 this process takes a 1h30 to create each machine.
2) on tab pools > new vm > template (centos_65_64bits)
2.1 default configuration : stateless
2.2 Here I created 3 virtual machines at once
2.3 this process takes only one minute
On the tab virtual machines I can see all virtual machines.
Pooled machines have different icon image
and description is different too:
machines generated from tab VM are described as clone/dependent
- clone is a phisical copy?
machines generated from tab POOL are described as thin/independent
- thin is a just a reference to template vm ? what is phisical? any
configuration file?
In practice, what is the difference between these machines ?
http://www.ovirt.org/Features/PrestartedVm
"Today there are 2 types of Vm pools:
1. Manual - the Vm is supposed to be manually returned to the pool. In
practice, this is not really entirely supported.
2. Automatic - once the user shuts down the Vm - it returns to the pool
(stateless)."
all vm created from pool are stateless ?
thanks

[ACTION REQUESTED] please review new oVirt look-and-feel patch
by Greg Sheremeta
Hi,
A while back, I sent out an email for the new oVirt look-and-feel feature [1]. The new look and feel patch is ready for both code and UI review. At this point we're not looking for design review, although you are welcome to suggest design improvements. I'm mostly looking for help regression testing the entire UI.
Especially if you're an oVirt *UI* developer, please download the patch and try it [2]. The patch introduces some new CSS globally, and I had to adjust many screens and dialogs. It's quite possible that there are dialogs that I don't know about, so if you maintain any especially-hidden dialogs, please try the patch and verify your dialogs look good.
And you can also just try out the patch to see the amazing new look and feel!
Thanks for your feedback.
Greg

Can you please check the contents of /rhev/data-center/<your nfs mount>/<nfs domain uuid>/ha_agent/?
This is how it should look like:
[root@dev-03 ~]# ls -al /rhev/data-center/mnt/euryale\:_home_ovirt_he/e16de6a2-53f5-4ab3-95a3-255d08398824/ha_agent/

-rw-rw----. 1 vdsm kvm 1028096 Mar 19 18:46 hosted-engine.metadata
The errors seem to indicate that you somehow lost the lockspace file.

hosted engine health check issues
by René Koch
Hi,
I have some issues with hosted engine status.
oVirt hosts think that hosted engine is down because it seems that hosts
can't write to hosted-engine.lockspace due to glusterfs issues (or at
least I think so).
Here's the output of vm-status:
# hosted-engine --vm-status
--== Host 1 status ==--
Status up-to-date : False
Hostname : 10.0.200.102
Host ID : 1
Engine status : unknown stale-data
Score : 2400
Local maintenance : False
Host timestamp : 1397035677
Extra metadata (valid at timestamp):
metadata_parse_version=1
metadata_feature_version=1
timestamp=1397035677 (Wed Apr 9 11:27:57 2014)
host-id=1
score=2400
maintenance=False
state=EngineUp
--== Host 2 status ==--
Status up-to-date : True
Hostname : 10.0.200.101
Host ID : 2
Engine status : {'reason': 'vm not running on this
host', 'health': 'bad', 'vm': 'down', 'detail': 'unknown'}
Score : 0
Local maintenance : False
Host timestamp : 1397464031
Extra metadata (valid at timestamp):
metadata_parse_version=1
metadata_feature_version=1
timestamp=1397464031 (Mon Apr 14 10:27:11 2014)
host-id=2
score=0
maintenance=False
state=EngineUnexpectedlyDown
timeout=Mon Apr 14 10:35:05 2014
oVirt engine is sending me 2 emails every 10 minutes with the following
subjects:
- ovirt-hosted-engine state transition EngineDown-EngineStart
- ovirt-hosted-engine state transition EngineStart-EngineUp
In oVirt webadmin I can see the following message:
VM HostedEngine is down. Exit message: internal error Failed to acquire
lock: error -243.
These messages are really annoying as oVirt isn't doing anything with
hosted engine - I have an uptime of 9 days in my engine vm.
So my questions are now:
Is it intended to send out these messages and detect that ovirt engine
is down (which is false anyway), but not to restart the vm?
How can I disable notifications? I'm planning to write a Nagios plugin
which parses the output of hosted-engine --vm-status and only Nagios
should notify me, not hosted-engine script.
Is is possible or planned to make the whole ha feature optional? I
really really really hate cluster software as it causes more troubles
then standalone machines and in my case the hosted-engine ha feature
really causes troubles (and I didn't had a hardware or network outage
yet only issues with hosted-engine ha agent). I don't need any ha
feature for hosted engine. I just want to run engine virtualized on
oVirt and if engine vm fails (e.g. because of issues with a host) I'll
restart it on another node.
Thanks,
René

1. Summary:
Updated qemu-kvm-rhev packages that fix several security issues are now
available for Red Hat Enterprise Virtualization.
The Red Hat Security Response Team has rated this update as having
Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
2. Relevant releases/architectures:
RHEV Agents (vdsm) - x86_64
3. Description:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package
provides the
user-space component for running virtual machines using KVM in
environments
managed by Red Hat Enterprise Virtualization Manager.
Multiple integer overflow, input validation, logic error, and buffer
overflow flaws were discovered in various QEMU block drivers. An attacker
able to modify a disk image file loaded by a guest could use these
flaws to
crash the guest, or corrupt QEMU process memory on the host, potentially
resulting in arbitrary code execution on the host with the privileges of
the QEMU process. (CVE-2014-0143, CVE-2014-0144, CVE-2014-0145,
CVE-2014-0147)
A buffer overflow flaw was found in the way the virtio_net_handle_mac()
function of QEMU processed guest requests to update the table of MAC
addresses. A privileged guest user could use this flaw to corrupt QEMU
process memory on the host, potentially resulting in arbitrary code
execution on the host with the privileges of the QEMU process.
(CVE-2014-0150)
A divide-by-zero flaw was found in the seek_to_sector() function of the
parallels block driver in QEMU. An attacker able to modify a disk image
file loaded by a guest could use this flaw to crash the guest.
(CVE-2014-0142)
A NULL pointer dereference flaw was found in the QCOW2 block driver in
QEMU. An attacker able to modify a disk image file loaded by a guest could
use this flaw to crash the guest. (CVE-2014-0146)
It was found that the block driver for Hyper-V VHDX images did not
correctly calculate BAT (Block Allocation Table) entries due to a missing
bounds check. An attacker able to modify a disk image file loaded by a
guest could use this flaw to crash the guest. (CVE-2014-0148)
The CVE-2014-0143 issues were discovered by Kevin Wolf and Stefan Hajnoczi
of Red Hat, the CVE-2014-0144 issues were discovered by Fam Zheng, Jeff
Cody, Kevin Wolf, and Stefan Hajnoczi of Red Hat, the CVE-2014-0145 issues
were discovered by Stefan Hajnoczi of Red Hat, the CVE-2014-0150 issue was
discovered by Michael S. Tsirkin of Red Hat, the CVE-2014-0142,
CVE-2014-0146, and CVE-2014-0147 issues were discovered by Kevin Wolf of
Red Hat, and the CVE-2014-0148 issue was discovered by Jeff Cody of
Red Hat.
All users of qemu-kvm-rhev are advised to upgrade to these updated
packages, which contain backported patches to correct these issues. After
installing this update, shut down all running virtual machines. Once all
virtual machines have shut down, start them again for this update to take

Re: [ovirt-users] Ovirt + GLUSTER
by Jeremiah Jahn
Nothing too complicated.
SL 6x and 5
8 vm hosts running on a hitachi blade symphony.
25 Server guests
15+ desktop windows guests
3x 12TB storage servers (All 1TB based raid 10 SSDs) 10Gbs PTP
between 2 of the servers, with one geolocation server offsite.
Most of the server images/luns are exported through 4Gbps FC cards
from the servers using LIO except the desktop machines with are
attached directly to the gluster storage pool since normal users can
create them. Various servers use use the gluster system directly for
storing a large number of documents and providing public access to
the tune of about 300 to 400 thousand requests per day. We
aggregate, provide public access, efiling, e-payments and case
management software to most of the illinois circuit court system.
Gluster has worked like a champ.
