[libvirt-users] virt-install on powerpc64 issues
by Alexey Kardashevskiy
Hi!
I am trying to setup a guest using virt-install script:
/usr/bin/virt-install -n fc18guest5 -r 1024 \
--disk path=/home/aik/virtimg/fc18guest,size=8 \
-c /home/aik/virtimg/Fedora-18-ppc64-DVD.iso \
--video vga --arch=ppc64 -d --machine=pseries
And it fails. I could not find any relevant log in /var/log/libvirt/ so I
simply hacked /usr/local/bin/qemu-system-ppc64 to print all the parameters
passed into it. So I got the command line (below, after the second
question) where the "-device scsi-cd" parameter is cut in a middle so QEMU
fails to start. 788 chars long - is there a limit?
The second question is - where does virt-install store those xmls? I have
to choose a new name for a machine even if virt-install failed, in the
example it is "fc18guest5" (5 at the end). "virsh -c qemu:///system list"
prints an empty list with no domains.
Thanks!

[libvirt-users] Port forwarding for KVM
by 陳韋任 (Wei-Ren Chen)
Hi all,
Let me illustrate what I want to do. I want to launch a QEMU
"inside" a KVM virtual machine, then get that QEMU's vnc output.
I am using libvirt 0.9.13 (`libvirtd --version`), and attach is
my vm's original config xml. Is there a simple way to achieve my goal?
I was told that iptable solution I found on the web is for "tap"
interface, and I can use "hostfwd" QEMU option if I use "user"
interface. For the latter approach, I basically follow this one [1]
with the QEMU cmdline option below:
<qemu:commandline>
<qemu:arg value='-net user,hostfwd=::5902-:5901'/>
</qemu:commandline>
But virsh always keep saying:
error: internal error Process exited while reading console log output:
kvm: -net user,hostfwd=::5902-:5901: invalid option
What I am missing here? I also found there was a patch for user mode
port forwarding [2]. Does that mean I can write libvirt xml directly
to do port forwarding? If so, could someone give me hint on how to
write one? The last question is, do I have to change the interface
type from "network" to "user" so that I can do port forwarding?
Thanks in advance! :)

[libvirt-users] Libvirtd dead, pid still exists. ( Problem might be with TLS interface of libvirtd )
by SHREE DUTH AWASTHI
Dear All,
Please find few minutes from your time and guide us with some pointers if
possible.
We are facing a libvirtd crash when we are trying to connect to qemu by
default TLS transport.
# virsh -c qemu+tls://localhost/system version
error: authentication failed: TLS handshake failed A TLS packet with
unexpected length was received.
error: failed to connect to the hypervisor
I used my own CA and certificates (generated using
http://libvirt.org/remote.html#Remote_libvirtd_configuration on Redhat PC)
on both Kontron PC and our Board (with patched libvirt). Libvirtd.conf was
modified so that libvirt is listening all IPs using default IP (so that it
was possible to use same certificates on all machines)
These directories and files created and used.
/etc/pki/CA/cacert.pem
/etc/pki/libvirt/private/serverkey.pem
/etc/pki/libvirt/servercert.pem
/etc/pki/libvirt/private/clientkey.pem
/etc/pki/libvirt/clientcert.pem
TLS connection worked fine with Kontron PC
# virsh -c qemu+tls://localhost/system version
Compiled against library: libvir 0.9.5
Using library: libvir 0.9.5
Using API: QEMU 0.9.5
Running hypervisor: QEMU 0.12.1
But libvirt crashed on our Board (using libvirt 0.10.2,
gnutls-2.10.5-1_WR4.3.x86_64 and libudev-161-4 rpms )
# virsh -c qemu+tls://localhost/system version
error: authentication failed: TLS handshake failed A TLS packet with
unexpected length was received.

[libvirt-users] Accessing libvirtd from multiple agents
by arvind viswanathan
Hi,
I was wondering if multiple remote agents can access the same libvirtd. How
do we prevent conflicting commands from the different agents. Can different
access permission be set for the agents? (The documentation usually goes
over the case where one agent can access multiple libvirtd and not this
case)
Thanks

by 邓焕聪
when i send a reboot command to libvirtd to reboot a domain, it does not receive and print the following warn:2013-04-10 06:01:39.080+0000: 2908: warning : qemuDomainObjTaint:1311 : Domain id=56 name='69751ca7-3198-4f3c-8265-cb8cb70ad750' uuid=69751ca7-3198-4f3c-8265-cb8cb70ad750 is tainted: high-privileges
