Loading the KVM module (Fedora 19 on ppc64, POWER7)
by Andrej Podzimek
Hello,
I'm trying to run libvirtd and KVM on a POWER7 machine. For some reason, virt-manager on a client says there is no KVM support. :-( The KVM module installed on the system cannot be loaded:
# modprobe kvm
modprobe: ERROR: could not insert 'kvm': Input/output error
There are no new messages in dmesg. Presumably, the file /lib/modules/3.10.11-200.fc19.ppc64p7/kernel/arch/powerpc/kvm/kvm.ko is readable; at least sha1sum can read it. This is how the error appears in strace (from open()ing the module to an unsuccessful kcmp()):
open("/lib/modules/3.10.11-200.fc19.ppc64p7/kernel/arch/powerpc/kvm/kvm.ko", O_RDONLY|O_CLOEXEC) = 3
read(3, "\177ELF\2\2", 6) = 6
lseek(3, 0, SEEK_SET) = 0
fstat(3, {st_mode=S_IFREG|0744, st_size=273976, ...}) = 0
mmap(NULL, 273976, PROT_READ, MAP_PRIVATE, 3, 0) = 0x1fffffad0000
kcmp(0x3, 0x1ffffff68330, 0, 0x3, 0) = -1 EIO (Input/output error)
The OS is a fresh Fedora 19 installation with kernel.ppc64p7 3.10.11-200.fc19.
Perhaps this could be a known issue or a glitch related to SELinux, but I have no idea what to try next. Could someone give me a hint, please?
Cheers!

Virtio-SCSI & Windows XP
by Jorge Fábregas
Hi,
Do "Windows XP" guests work with the new virtio-scsi? Do we use the same
old virtio drivers during installation?
Thanks,

Specify disk-image format on Virt-Manager
by Jorge Fábregas
Hi,
Are there plans to enhance virt-manager so that it allows you to specify
the disk format during the VM-creation wizard? I create a lot VMs with
virt-install (where I can specify it) but I also use virt-manger once in
a while and would be great if we could specify it there (without first
creating the disk image beforehand).
I saw an enhancement-request but it was closed as it was for RHEL5.
Thanks,
Jorge

WinXP & Slow Network Startup (BallonService)
by Jorge Fábregas
Hi everyone,
I'm running Fedora 19 (with Preview Repo) and just installed Windows XP
(media already had SP3) and applied all 100+ updates (no additional 3rd
party software installed) with VirtIO (on Net & SCSI controller). I'm
running the latest virtio drivers.
I proceeded to install the SPICE Agent Tools and rebooted the VM and now
I can copy/paste from guest to host (very cool). However, I noticed
that the network takes about 1.5 minutes to start. I have the "show
icon when connected option" and literally takes 1.5 minutes. I
searched the mailing list's archive and there was a similar post but
apparently the situation there was related to the .NET framework (which
I don't have installed).
After some trial & error I finally pinpointed the problem to the
"BallonService" installed by the SPICE tools. If I set the service to
"disabled" and reboot the VM the network starts right away.
Has anyone bumped into this?
Regards,
Jorge

[deadline in 1 week] 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)
held in conjunction with SC 13, Denver, Colorado | in cooperation with
ACM SIGHPC
=================================================================
Date: November 22, 2013
Workshop URL: http://vhpc.org
Paper Submission Deadline: September 23, 2013 (firm)
Invited Talks:
- John Goodacre, Director, Technology and Systems, ARM Processor Division
The Evolution of the ARM Architecture Towards Big Data and the Data-Centre.
- Jacob Bower, VP of Application Engineering, Maxeler Technologies Ltd.
Maximizing Performance with cloud-virtualized Dataflow Engine oo-processors.
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
high-throughput 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

Fedora 19 & Latest libvirt/qemu
by Jorge Fábregas
Hi,
What repo can I configure in order to run the latest libvirt & qemu
packages with Fedora 19? I know I've seen it mentioned before but can't
find it.
Thanks,

Virtualization Package Groups
by Jorge Fábregas
Hi,
What happened to the yum package groups: "Virtualization Platform",
"Virtualization Client", "Virtualization Tools" etc...? They seemed to
be a nice way of grouping the packages. All I see now in Fedora 19 is
the plain "Virtualization" group. (I'm moving away from Fedora 14).
Thanks,
Jorge

Sanlock + libvirt
by Ján ONDREJ (SAL)
Hello,
in sanlock docs (https://fedorahosted.org/sanlock/) there is described,
how to use it. There is no mention about NFS. Can I use sanlock with LVM
(without NFS) with livbirt? It this feature implemented in libvirt for
Fedora or RHEL?
For libvirt I need to define lease dir as:
disk_lease_dir = "/var/lib/libvirt/sanlock"
but this have to be a directory. How to configure it to use sanlock on LVM?
