RHEL 5.9 guest X server error 11 under Fedora 19 virt
by Michael Brown
Have Fedora 19 x86_64 installed, up-to-date with updates. Also have
Virtualization installed.
I have downloaded both RHEL 6.4 x86_64 and RHEL 5.9 x86_64 directly from
RHN.
RHEL 6.4 installs fine. After install, the install boots into the normal
gnome interface
RHEL 5.9 does not. First hint of issue is during install when it reports
an X Server failure to start, and the full graphical install does not
load. A more limited graphical install proceeds. When the install
finishes, and after reboot, it boots into init 3. When I attempt to
perform an init 5, X fails to start and it reports an error 11, which I
believe to be a segmentation fault.
Previously the RHEL 5 guest install worked under Fedora 16, 17, and 18 virt.
Has anyone seen the above, and know how to resolve in Fedora 19?

Error creating a vol on a disk type storage pool with multipath'ed backend
by Shergill, Gurinder
Hello,
When I use a disk type storage pool that uses a multipath'ed backend, I am getting the following failure as I try to create the vol (or when I try to start the pool with existing partitions on the backend).
$ virsh vol-create-as poolname vol1 10G
error: Failed to create vol vol1
error: cannot stat file '/dev/mapper/mpathap1': No such file or directory
The partition is created successfully and the DSF for it is /dev/mapper/mpatha1 (has no "p").
Here is the pool definition:
<pool type="disk">
<name>poolname</name>
<source>
<device path="/dev/mapper/mpatha"/>
<format type="gpt"/>
</source>
<target>
<path>/dev</path>
</target>
</pool>
I also tried passing /dev/mapper as the target path but got the same failure. Interestingly, things work fine when I take multipath/dm out of the picture. This is happening on F19 with the latest set of packages.
I enabled debug logging to collect more information. Here are some debug messages that seemed interesting (let me know if you need the full log and I can send it as well).

CfP 8th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '13)
by VHPC 15
we apologize if you receive multiple copies of this CfP
=================================================================
CALL FOR PAPERS
8th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '13)
as part of SC 13, Denver, Colorado | sponsored by ACM sighpc
=================================================================
Date: November 22, 2013
Workshop URL: http://vhpc.org
Paper Submission Deadline: September 23, 2013
CALL FOR PAPERS
Virtualization has become a common abstraction layer in modern data
centers, enabling resource owners to manage complex infrastructures
independently of their applications. Conjointly, virtualization is becoming
a driving technology for a manifold of industry grade IT services. The
cloud concept includes the notion of a separation between resource
owners and users, adding services such as hosted application
frameworks and queueing. Utilizing the same infrastructure, clouds
carry significant potential for use in cpu-intensive or data-intensive
computing. The ability of clouds to provide for requests and releases
of vast computing resources dynamically and close to the marginal
cost of providing the services is unprecedented in the history of
scientific and commercial computing.
This workshop aims to bring together industrial providers with the
application community in order to foster discussion, collaboration
and mutual exchange of knowledge and experience.
The workshop will be one day in length, composed of 20 min paper
presentations, each followed by 10 min discussion sections. Lightning
talks are limited to 5 minutes. Presentations may be accompanied by
interactive demonstrations.

xen 4.3.0 on Fedora 20
by M A Young
I have now updated xen on Fedora 20 to version 4.3.0. I have built it with
the XSM/FLASK security subsystem available if you add a xenpolicy file as
a module in the grub configuration. Note that the xen-hypervisor package
on i686 is currently empty because it was dropped in this version, but a
32-bit dom0 should work on a 64-bit hypervisor if your hardware supports
it.

Isolated Virtual Network
by Dean Hunter
I have a Fedora 18 server hosting several Fedora 18 guests with a
bridge. The server, guests of the server, and peers of the server can
all freely interact. I have YUM repositories available via http and
home and shared directories available via nfs from the server. And DNS,
authentication and policies for autofs and sudo are available from IPA
on one of server guests. Life is good.
[root@host ~]# cat /etc/sysconfig/network-scripts/ifcfg-em1
# Configured manually
BRIDGE=br1
DEVICE=em1
HWADDR=00:1C:C4:AE:57:4F
ONBOOT=yes

<bridge name='br1' />
<mac address='52:54:00:18:8F:47'/>
</network>
[root@host ~]#
Now Fedora 19 comes along and I need to test new versions of the server
guests in isolation from existing server guests and server peers; ie.
everything except for the http and nfs services of the server. I
welcome your suggestions.

xinit, Spice and sound
by Eric Viseur
Hi,
Back with one more (probably last for the moment) problem, with sound this
time.
When I connect to a Windows 7 (ich6 audio device) with virt-manager or
spicec from Gnome, sound works like a charm.
However, for the intended use, my standard boot sequence is booting Fedora
in the multi-user.target (runlevel 3), and run spicec with xinit.
In this situation, I logically get a connection refused to pulseaudio since
it isn't running. If I start pulseaudio with start-pulseaudio-x11 as the
user running spicec, I don't get any errors, but no sound either.
I know this has more to do with pulseaudio than virtualization, however,
since I know sound has been a long time issue with Spice on previous
versions, maybe someone can help me on this ?
Thanks in advance !
Regards,
Eric Viseur

fedora 19 virt-viewer VNC corruption
by Chuck Anderson
I installed Fedora 19 and moved the VMs I was running on Fedora 17
previously to it. The VNC display is now corrupted--the desktop
background is black and many widgets (the guest is Windows XP), making
it pretty unusable. Basically, it looks like it is failing to paint
large blocks of the UI, but sometimes pieces of it reappear when
clicking on menus, etc. Is this a known issue with Fedora 19
virt-viewer & VNC displays?
I tried getting Windows XP to install the Spice driver, but had
problems way-back-when. I suppose I could try again if VNC is no
longer supported.

Virtual COM ports on Win7
by Eric Viseur
Hi,
I'm having another problem with my KVM setup, using Fedora 18. For
debugging pruposes, I added two serial ports to my virtual machines, like
this :
<serial type="pty">
<target port="1 (or 2)" />
</serial>
On the Linux guest, everything works fine. On the Windows 7 guest, I only
get one of the two ports. The one showing up works well, but I don't
understand why the second one doesn't show up. libvirt reports the
creation of the char devices on the logs, without any error.
Couldn't find anything about this on Google. Any clues ? Thanks !

Spice problem
by Eric Viseur
Hi,
I'm currently setting up a virtualization system using Fedora 18, KVM and
Open vSwitch. I've created and successfully integrated my OVS bridge into
libvirt. However, if this bridge doesn't have an assigned IP address (and
it won't in production mode), I can't start any VM, with Spice complaining
with the following error :
((null):6425): Spice-Warning **:
reds.c:2977:reds_init_socket: getaddrinfo(127.0.0.1,5900): Address family
for hostname not supported
qemu-kvm: failed to initialize spice server
I don't understand from where it comes, since the local loop interface is
up. Can anyone help me on this ? Thanks !

Windows clock synchronization
by Ján ONDREJ (SAL)
Hello,
I have clock synchronization problems with Fedora 18/KVM host and windows
server guests. Different 64bit windows servers, all has some time
synchronization problems.
Some of them will slow down time until time difference is 60 seconds and
then clock is synchronizes from internet. But 60 seconds is a long time.
Kerberos authentication sometimes files due to time skew.
Some machines will run OK day or two, but then clock stops. After some
hours clock is synchronized again and continues to work properly.
Curious, that during time is stopped, server works properly (except kerberos
authentications, which is very time sensitive.
For example, attaching 2 graphs from 2 windows servers. They show time
difference measured by check_mk nagios plugin. 10k means 10000 seconds.
How I should set clock/time/NTP on these guests?
I have absolutelly no problems with Linux guests, they work perfectly.
Thank you.
