Hi All,
my name is Peter van der Meulen from the Netherlands. I'm (self paced) studying the RHEV guides and course material to take the RHEV certifiation exam. Installing the RHEV manager is not a problem, the hypervisor is, however, another story. I don't have a seperate physical machine for the hypervisor. I was told that it is possible to install the RHEV hypervisor in a virtual machine using Ovirt kernel modules. Could someone point me towards documentation on this issue and what kernel modules to install? Thanks in advance!
Best regards,
Peter

[Users] usb passthough permission
by lof yer
I add a qemu-cmd hook to localhost.
"-device usb-host:vendorid=0718,productid=0083"
And in the qemu/usb-test.log I find
"....
Domain id=6 is tainted: custom-argv
husb: open device 2.7
/dev/bus/usb/002/007: Operation not permitted
husb: open device 2.7
/dev/bus/usb/002/007: Operation not permitted

qemu: terminating on signal 15 from pid 3534
2013-10-31 05:48:36.483+0000: shutting down"
I'd set setuid of /usr/libexec/qemu-kvm, is there some other configuration?

[Users] oVirt 3.3.1, RHEL 6.5 (beta) and Gluster SD
by Samuli Heinonen
Dear all,
i'm testing QEMU-Gluster features with oVirt 3.3.1 beta and RHEL 6.5 beta. For reason or another it seems to bypass Gluster support in QEMU and use VM image through FUSE mount point instead.
ie. Libvirt XML shown in vdsm.log looks like this:
<disk device="disk" snapshot="no" type="file">
<address bus="0x00" domain="0x0000" function="0x0" slot="0x06" type="pci"/>
<source file="/rhev/data-center/mnt/glusterSD/boar1.storage:dev-el6-sata1/402a2eee-40f6-4012-b188-63ec122ce399/images/f6ba1575-e6de-428c-93ef-8a27cf23de61/bc3de195-ccc4-4202-ade2-7e4d0cdb292e"/>
<target bus="virtio" dev="vda"/>
<serial>f6ba1575-e6de-428c-93ef-8a27cf23de61</serial>
<boot order="1"/>
<driver cache="none" error_policy="stop" io="threads" name="qemu" type="raw"/>
</disk>
and also qemu-kvm process for this VM has option "-drive file=/rhev/data-center/mnt/glusterSD/boar1.storage:dev-el6-sata1/402a2eee-40f6-4012-b188-63ec122ce399/images/f6ba1575-e6de-428c-93ef-8a27cf23de61/bc3de195-ccc4-4202-ade2-7e4d0cdb292e,if=none,id=drive-virtio-disk0,format=raw,serial=f6ba1575-e6de-428c-93ef-8a27cf23de61,cache=none,werror=stop,rerror=stop,aio=threads"
oVirt 3.3 and Fedora 19 works as intended. Any ideas what might be wrong?
Steps to reproduce (hopefully?):
1: Clean install of ovirt-engine 3.3.1 beta on CentOS 6.4
2: Clean install of RHEL 6.5 beta with EPEL, Gluster-epel and oVirt repos enabled (and all necessary Red Hat channels.)
3: Install RHEL 6.5 host to oVirt and let it install necessary packages
4: Switch datacenter storage type from NFS -> GlusterFS
5: Insert storage domain
6: Start installing virtual machines
Please let me know if more information is needed or you want me to open a bug report for this.

[Users] Old Alerts Present
by Mark Shields
Running oVirt Engine 3.3.0-4.el6 on CentOS 6.4.
These alerts are no longer valid; the host 'virt03' is responding and
running VMs. No new ones have happened since. I've looked all over but
not found a way to clear these. Any ideas?

manually.

Failed to power fence host virt03. Please check the host status and it's
power management settings, and then manually reboot it and click
"Confirm Host Has Been Rebooted"

[Users] ovirt-guest-agent issue/troubleshooting
by René Koch (ovido)
Hi,
I have some issues with ovirt-guest-agent as no information is reported
from guest-agent to oVirt webadmin anymore.
I'm unsure when I lost the information - I know for sure it worked last
month when I tested the guest agent packages for Debian and Ubuntu.
Status now is that I don't receive any data.
I have the following test vms:
* RHEL 6 with rhevm-guest-agent 1.0.7 (RHEV repository)
* RHEL 6 with ovirt-guest-agent 1.0.8 (EPEL)
* openSUSE 12.3 with ovirt-guest-agent 1.0.8.1 (self compiled)
Both RHEL server reported information (memory, ip-address,...)
previously.
The only changes which could broke the guest agent communication are
updates on the CentOS host and the engine.
Can you give me some hints how to troubleshoot the guest agent? I can't
find any information (or don't know the right pattern to search for) in
vdsm.log and engine.log. Guest agent is running in the vms, but doesn't
log anything except start and stop of the service (can I change the
handler_logfile args for more debugging and if yes how?):
# tail /var/log/ovirt-guest-agent/ovirt-guest-agent.log
MainThread::INFO::2013-10-29
11:00:15,340::ovirt-guest-agent::37::root::Starting oVirt guest agent
Btw, I'm running oVirt 3.2.3...
Thanks a lot,
René

Re: [Users] problem with engine 3.3 on f19 and java path after update
by Owen Williams
Hello,
Sorry for the poor threading. I've just joined the list.
I edited:
/etc/ovirt-engine/notifier/notifier.conf.d/10-setup-java.conf
/etc/ovirt-engine/engine.conf.d/10-setup-java.conf
to fix this. This got ovirt-engine going again but the web interface
doesn't work yet...
Best regards,
Owen.

[Users] libgovirt 0.3.0

About libgovirt
===============
libgovirt is a GObject-based library to access oVirt REST API. It uses
GObject and librest to integrate well with GNOME applications.
News
====
Changes since 0.2.0:
- Add support for listing storage domains and the files they contain
- Add support for changing the CDRom available in a VM
- Introduced an OvirtApi class which represents the toplevel oVirt
collection from which one can access VMs, storage domains, ...
This means that various OvirtProxy methods to fetch VMs have been deprecated
in favour of using OvirtApi + OvirtCollection methods
- Rework certificate handling, OvirtProxy now has a 'ssl-ca-file' property
that can be used to specify which CA certificate should be used to validate
remote certificates.
- Certificate checking is now enforced by default unless
OvirtProxy::ssl-strict is set to FALSE
- ABI/API hasn't been broken, even though some functions were deprecated
