[Users] Unable to delete a snapshot
by Nicolas Ecarnot
Hi,
With our oVirt 3.3, I created a snapshot 3 weeks ago on a VM I've
properly shutdown.
It ran so far.
Today, after having shut it down properly, I'm trying to delete the
snapshot and I get an error :
"Failed to delete snapshot 'blahblahbla' for VM 'myVM'."
The disk is thin provisionned, accessed via virtIO, nothing special.
The log below comes from the manager.
I hope someone could help us because this server is quite serious.
Thank you.

[Users] oVirt Node Bootloader issue
by Nauman Abbas
Hello there
I'm facing this problem and this has happened to me multiple times on
different machines. I have two hard drives in my system (lets say HDD A and
HDD B). I boot the system from the oVirt node CD to install it. Now I want
the bootloader and the node installation both to go on HDD B and not HDD A.
When I get to the screen which asks me to select the hard-drive for
bootloader I use the arrow keys to select HDD B and press Enter (have also
tried pressing space or just use tab and continue while it's selected).
Then I get to the screen asking where to install the node. I select HDD B
and unselect HDD A. I keep the partitioning setup as default ( have also
tried manual and kept 5GB unused on HDD A). When I get to install part. It
installs the node fine on HDD B as expected but it always gets the
boot-loader on HDD A. This issue has wasted many of my days on different
machines and I can't seem to find a way around.

[Users] VM Status "Unknown"

During a migration, the destination host lost connectivity to the san and c=
rashed.
Once the server came back up, 3 VMs that didn't finish migrating have been =
stuck in status "Unknown." Vdsclient doesn't list any of the vms on eithe=
r host. Qemu doesn't have them listed as mounted on either host. Action =
vm start and stop result in "Status: 409".
The disks for all 3 VMs are listed as green in the WebAdmin. I've tried "a=
ction vm <name> start" "action vm <name> stop" "update vm <name> --status-=
state down" no joy. They remain in "unknown."

Hi,
I have an ovirt 3.1 build. I have 3 hosts and a few virtua=
l machines setup that I am using for testing. I am using gluster storage s=
etup as a distribution between the 3 hosts. I can migrate linux guests acr=
oss my 3 hosts, but I cannot migrate windows hosts. I get "Migration faile=
d due to Error: Fatal error during migration. The event id is 65. Is ther=
e something additional that needs to be done to windows guests for them to =
support live migration?
Thanks,

[Users] Vm's being paused
by Neil
Hi guys,
I've had two different Vm's randomly pause this past week and inside ovirt
the error received is something like 'vm ran out of storage and was
paused'. Resuming the vm's didn't work and I had to force them off and then
on which resolved the issue.
Has anyone had this issue before?
I realise this is very vague so if you could please let me know which logs
to send in.
Thank you
Regards.

[Users] API read-only access / roles
by Sander Grendelman
I'm working on (Zabbix) monitoring through the RESTful API.
Which role should I assign to the monitoring user?
The user only needs read access to the data but it looks like
I nead to assign at least an "Admin" role to the user to be
able to read data through the API.
For this I've created a "AdminLoginOnly" role that only has
System->Configure System->Login Permissions access.
Is this the way to go for this king of configuration? Or is there
a way to further minimize the permissions of this user?
Another issue is that a "Login" event is generated every time
the user connects through the API. This makes the "Events"
pane less useful / readable. Is there a way to disable this for
some users/roles?

[Users] "Volume Group does not exist". Blame device-mapper ?
by Nicolas Ecarnot
Hi,
oVirt 3.3, no big issue since the recent snapshot joke, but all in all
running fine.
All my VM are stored in a iSCSI SAN. The VM usually are using only one
or two disks (1: system, 2: data) and it is OK.
Friday, I created a new LUN. Inside a VM, I linked to it via iscsiadm
and successfully login to the Lun (session, automatic attach on boot,
read, write) : nice.
Then after detaching it and shuting down the MV, and for the first time,
I tried to make use of the feature "direct attach" to attach the disk
directly from oVirt, login the session via oVirt.
I connected nice and I saw the disk appear in my VM as /dev/sda or
whatever. I was able to mount it, read and write.
Then disaster stoke all this : many nodes suddenly began to become
unresponsive, quickly migrating their VM to the remaining nodes.
Hopefully, the migrations ran fine and I lost no VM nor downtime, but I
had to reboot every concerned node (other actions failed).
In the failing nodes, /var/log/messages showed the log you can read in
the end of this message.
I first get device-mapper warnings, then the host unable to collaborate
with the logical volumes.
The 3 volumes are the three main storage domains, perfectly up and
running where I store my oVirt VMs.
My reflexions :
- I'm not sure device-mapper is to blame. I frequently see device mapper
complaining and nothing is getting worse (not oVirt specifically)
- I have not change my network settings for months (bonding, linking...)
The only new factor is the usage of direct attach LUN.
- This morning I was able to reproduce the bug, just by trying again
this attachement, and booting the VM. No mounting of the LUN, just VM
booting, waiting, and this is enough to crash oVirt.
- when the disaster happens, usually, amongst the nodes, only three
nodes gets stroke, the only one that run VMs. Obviously, after
migration, different nodes are hosting the VMs, and those new nodes are
the one that then get stroke.
This is quite reproductible.
And frightening.
