[Users] Bug related to Rhevm/Ovirt auto update or refresh !!
by Romil Gupta
Hello,
I upload ISO image using this script *upload.py*:
==================================================================================
import os
os.system('mkdir mount_dir')
os.system('mount -t nfs 15.15.158.2:/iso/rhevmisonfs mount_dir')
print 'mounted'
print 'start copying'
os.system('cp -f CentOS-6.2-x86_64-LiveDVD.iso
mount_dir/e3e3b0cd-48a4-4bb8-a75b-07813f2c165e/images/11111111-1111-1111-1111-111111111111/')
print 'file copied'
os.system('umount -a nfs 15.15.158.2:/iso/rhevmisonfs mount_dir')
print 'unmounted'
os.system('rmdir mount_dir')
print 'dir removed'
==================================================================================
and I created a *rhevm_test.py *
api.vms.add(params.VM(name=VM_NAME,
memory=2*GB,os=params.OperatingSystem(boot=[params.Boot(dev='cdrom'),
params.Boot(dev='hd')]),cluster=api.clusters.get(name='Default'),
template=api.templates.get('Blank')))
print 'VM created'
domain=api.storagedomains.list()
for d in domain:
print ' domain name : %s ' %d.name
api.storagedomains.get(name='rhevmiso').update()
rhevmiso=api.storagedomains.get(name='rhevmiso').files.list()
for iso in rhevmiso:
print ' iso --> %s \n' % iso.name
image = api.storagedomains.get(name='rhevmiso').files.get(name='
CentOS-6.2-x86_64-LiveDVD.iso ')
print 'image found %s' %image
api.vms.get(VM_NAME).cdroms.add(params.CdRom(name='cdrom',file=image))
print 'image added to VM'
==================================================================================
now i got the following exception :
image found none
*Note* : the reason is image is copied to "rhevmiso" storage domain but it
not reflected in RHEVM user interface unless and untill I refresh it !
whenever listing files in api should force iso-refresh but its not working
:(
*Do we have any refresh or update function in ovirt sdk so that after
coping the image RHEVM ISO domain will get refresh automatically ?? *

[Users] tool engine-manage-domains
by victor nunes
I'm trying to change the default domain, the "internal" with the following
command:
engine-manage-domains -action=edit -domain=internal
However, i am getting the following message:
"Domain internal doesn't exist int the configuration"
This is my domain admin user that is configured in the installation
ovirt-setup.
So, how can i fix it to include a user in this domain?

[Users] Why VDSM daemon resets SATA link too often
by Adam Tkáč
Hello all,
I'm experiencing strange issue on one of the nodes. There is only one
VM on the node but it generates _a lot_ of disk I/O.
Sometimes vdsm writes following error to the system log:

The "752f4ef6-2e3a-4cec-aad9-848a8b8b9e80" is LOCALFS storage and VM
image is stored there.
After that VM becomes unresponsible and I have to kill qemu-kvm
process manually. The VM's image is stored on XFS system and after
SATA reset it takes some time before XFS responds. During this time
libvirtd daemon is not responsible and vdsm timeouts.
Is it possible to configure vdsm not to reset SATA link every time
when it starts? And if not, is it possible to increase timeout how
long vdsm waits for libvirtd response?
Thank you in advance.

[Users] Installing ovirt-nightly problems
by Joop
Since I had some problems getting bonding working correctly in my
ovirt-3.1 test installation I decide to start all over with a clean
install and try the nightly, the webcast about bonding is using a nightly.
That didn't go to well :-(
What I did:
- install Fedora-17 from live CD
- yum upgrade --exclude=kernel*
(stayed on 3.3.4-5)
- yum localinstall http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm
- enabled nightly in ovirt.repo
- yum install ovirt-engine
Ended up with the following nightly rpms:
ovirt-engine-3.1.0-3.20121031.gitdd0ad7f.fc17.noarch

ran engine-setup and gave default answers where possible.
Instalation stopped with a Creating Database... ERROR
Attached are the logs and the real error is in the enginedb log:
user name is: engine
Creating uuid-ossp extension...
psql:/tmp/tmp.8hb5EYqc0Y:1: ERROR: permission denied to create extension
"uuid-ossp"
HINT: Must be superuser to create this extension.
It is right, user engine isn't a superuser and thus not allowed to create
the extension.
I modified the CREATE ROLE statement to include SUPERUSER role and
restarted engine-setup, now it continues and runs til the end.
Looking at the code I think that the second invocation of creating the
uuid-ossp extension isn't needed but commenting that line gives an error
too.
Looking at ovirt-stable and comparing the scripts in
/usr/share/ovirt-engine does show some changes but I don't know enough
internals to see what changed that causes this.

[Users] Ovirt-nightly and gluster
by jvandewege
I have an question regarding ovirt-nightly and the use of gluster.
If I modify the CREATE ROLE to add SUPERUSER I can install ovirt-nightly
and if I add my two storage hosts I can create a bond and add an ip
address and it will be displayed in the webui. Further the static ip
assignment of the ovirtmgmt interface doesn't fallback to DHCP like in
ovirt-stable. Sofar OK.
Now I want to use gluster for my two storage hosts. Can I do that with
the versions of vdsm that are pushed to the hosts by ovirt? (All
machines are basic Fedora 17 installs, upto date except for the kernel
which is 3.3.4-5) and gluster-3.3.1-2 from
baseurl=http://repos.fedorapeople.org/repos/kkeithle/glusterfs/fedora-$re...
Or do I need more recent versions of vdsm/libvirt/qemu?
Thanks in advance,
Joop
