[Users] Replacing ISO domain
by Gabi C
Hello!
1 Ovirt-engine + 2 nodes with Glusterfs on them (replicate), 1 ISO domain,
1 Export domain.
ISO domain is created at ovirt-setup time on ovirt-engine host.How can I
replace this ISO domain with a new, bigger, one on another machine?

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."

[Users] Creation of preallocated disk with Gluster replication
by gregoire.leroy＠retenodus.net
Hello,
I have a Gluster volume in distributed/replicated mode. I have 2 hosts.
When I try to create a VM with a preallocated disk, it uses 100% of the
available CPU and bandwidth (I have 1 Gigabit network card).
The result is I can't even create a preallocated disk because the engine
detects a network failure.
I get that kind of messages in /var/log/messages :
"
Jan 2 14:13:54 localhost sanlock[3811]: 2014-01-02 14:13:54+0100 167737

"
And that in the Ovirt Gui :
"

defined threshold [95%].
2014-janv.-02, 15:33 Add-Disk operation of test_Disk1 was initiated on
VM test by admin@internal.
I understand that the creation of a 10 Go disk image generates a lot of
traffic, but is there a way to limit it so that it doesn't have an
impact on the production ? Furthermore, Why does it use so much CPU
ressources ? I can see on my monitoring graph a big peak of CPU usage
when I launched the operation (probably until 100%).
Thank you,
Regards,

[Users] alx driver causes network troubles on VMs after bonding

Kernel driver in use: alx
When I bond it on the ovirtmgmnt network (two gigabit bond) VMs on local
cluster run OK but they fail to mount some gluster mount points
I suppose this is related to the alx driver which seems to be not
completely working (it still misses counters)
Bringing down the relevant interface so that the bond remains with only
one NIC (ifdown p4p1) fixes the issue.
So be warned: if you have this hardware check very carefully your
network mount points inside Vms
If you have already tested this configuration and have this working
please let me know.
Best regards

[Users] Specifying values for cert, key, and CA for ovirt-shell
by Bob Doolittle
Hi,
I want to run ovirt-shell directly (as root) on the Engine. Presumably
all the files I need for CA, key, and cert are in the /etc/pki area.
But when I use the attached .ovirtshellrc file I get:
error: [Errno 336265218] _ssl.c:341: error:140B0002:SSL
routines:SSL_CTX_use_PrivateKey_file:system lib
How can I specify an appropriate configuration to get this working?
I would prefer to keep using SSL if possible.
Thanks,
Bob

[Users] Bug? in tweak vm instance via REST/JSON 3.3.2
by Sven Kieske
Hi,
we got a problem with starting a vm after changing some of its
parameters via REST (JSON)
this is the command to create the vm (this works):
POST request on https://virt-mgmt-01.internal/api/vms/
{"name":"vr00002","cluster":{"id":"2ad11b5e-9e74-499a-b317-5a9a3027cfca"},"template":{"id":"374a12df-5ffc-4feb-a2bf-c912f059675f"}}
Then we tweak memory and cpu:
PUT request on
https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f
{"memory":2048,"cpu":{"topology":{"sockets":1,"cores":1}}}
and then we start it:
POST request on
https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47...
{"vm":{"initialization":{"cloudInit":{"host":{"address":"vr00002"},"networkConfiguration":{"nics":{"nics":[{"name":"eth0","bootProtocol":"STATIC","network":{"ip":{"address":"10.0.1.12","netmask":"255.255.255.252","gateway":"10.0.1.9"}},"onBoot":true}]},"dns":{"servers":{"hosts":[{"address":"46.30.62.99"},{"address":"46.30.62.98"},{"address":"46.30.62.97"}]}}},"users":{"users":[{"name":"root","password":"lPzYG06qV63+Tne7"},{"name":"vr00002","password":"lPzYG06qV63+Tne7"}]},"files":{"files":[{"name":"\/foo\/ip-configuration","content":"extern_v4address1
185.15.194.7\npassword1 lPzYG06qV63+Tne7","type":"PLAINTEXT"}]}}}}}
the error we get:
Operation Failed","detail":"[Cannot run VM. There is no host that
satisfies current scheduling constraints. See bellow for details:]"
when we start the vm without altering memory and cpu it starts just
fine.
Is this not supported via JSON, or is this a bug?
PS:
BTW there seems to be a spelling bug in the error message ("bellow").

[Users] Experience with low cost NFS-Storage as VM-Storage?
by Sven Kieske
Hi,
I'd like to ask around if someone does run oVirt
with NFS backed Storage provided by simple servers (no SAN or NAS)
and what your experience is so far?
In particular I'm interested what happens if there is a connection
loss to the NFS-Volume.
How does this affect running vms and the compute nodes they run on?
I suspect they would first write their changes to RAM instead of virtual
HDD.
But once the RAM is full, does just the vm become unresponsive or
does the whole compute node die?
I couldn't test this yet myself, but my limited experience with
NFS-Servers tells me, that they become unresponsive if they are under
heavy load and I'd like to know how this affects the vms and
computenode.
Thanks!
PS: Bonus question: Does someone utilize the NFS-Servers also as
computenodes ?
