[libvirt] Remote virConnect.listDomainsID() returns invalid IDs (Python, Xen)
by Russell Haering
I'm working with the Libvirt Python bindings and have discovered the
following:
If I run virConnect.listDomainsID() locally I get a list of valid IDs.
For example:
>>> import libvirt
>>> conn = libvirt.open('xen://')
>>> conn.listDomainsID()
[0, 35, 36, 37, 38, 39, 40, 61]
If I run the exact same thing remotely I get a list including numerous
invalid IDs. This example shows the same host as shown above, about 20
seconds earlier (everything essentially identical):
>>> import libvirt
>>> conn = libvirt.open('xen+tls://xxxx.xxxxx')
>>> conn.listDomainsID()
[0, 35, 36, 37, 38, 39, 40, 51, 52, 53, 54, 60, 61]
IDs 51, 52, 53, 54 and 60 are invalid.
I first noticed this problem working with libvirt 0.6.0 on the client
and 0.6.2 on the server, and noticed that with those versions the
problem also occurred with virsh.
Locally(0.6.0):
local ~ # virsh list
Id Name State
----------------------------------
0 Domain-0 running
35 xxxxxxx idle
36 xxxxx idle
37 xxxxxx idle
38 xxxxxxxxx idle
39 xxxxxx idle
40 xxxxx idle
61 xxxxxxxxxx idle
Whereas remotely(0.6.0):
remote # virsh -c xen+tls://xxxxx.xxxxx list
Id Name State
----------------------------------
0 Domain-0 running
35 xxxxxxx idle
36 xxxxx idle
37 xxxxxx idle
38 xxxxxxxxx idle
39 xxxxxx idle
40 xxxxx idle

However with virsh 0.6.2 on the client this appears to be fixed.

[libvirt] Has anyone ever gotten the client or full to compile on OS X?

It's me. The original instigator of the long Leopard thread from early
2008. I once again need to do libvirt development from my Mac, and I
still cannot seem to get it to compile :(
It is currently bugging out at:

Any help is appreciated.

[libvirt] LibvirtException: socket closed unexpectedly
by Marcel Michelmann
Hi *,
I wrote a program in Java communicating with libvirt/XEN over SSH, with
libvirt-java-0.2.1.
I poll the CPU and RAM usage quite often (about 5 times a second).
My program runs well about between 5-8 minutes, but then I get
LibvirtException: socket closed unexpectedly.
Although I try to catch the LibvirtExceptions with special
System.out.println messages I have no idea where this is coming from.
Now my question: what leads to this exception?
exception caught: org.libvirt.LibvirtException: socket closed unexpectedly
level:VIR_ERR_ERROR
code:VIR_ERR_RPC
domain:VIR_FROM_REMOTE
hasConn:false
hasDom:false
hasNet:false
message:socket closed unexpectedly
str1:%s
str2:socket closed unexpectedly
str3:null
int1:0
int2:0
After that I can start my program again, and it is the same again (runs some
minutes and then throws the exception).
Perhaps someone knows? I would be very thankful for any help!
Best regards,
Marcel

lxc_container.c:657: error: for each function it appears in.)
Apparently, my machine doesn't have the PR_CAPBSET_DROP flag defined.
It's inexistent in sys/capability.h and "man prctl".
I run a Ubuntu 8.04, kernel is 2.6.24-24-openvz.
Am I missing headers that are not tested for in the ./configure ? If
not, any way that functionality could be disabled on distros that don't
support it ?
Thanks,
Florian

[libvirt] create domain for existing xp image
by Gunnar Thielebein
I want to create a domain for an existing xp machine via virt-install.
The command is taken from this wiki article
http://wiki.libvirt.org/page/QEMUSwitchToLibvirt:
> virt-install --accelerate --hvm --connect qemu:///system -n xp -r 512
> --cdrom=/dev/null --file=WinXP.img --vnc --noautoconsole --os-type
> windows --os-variant winxp --force
When I start and connect I see message:
> We apologize for the inconvenience,
> ...
> A recent hardware or software change might have caused this.
When I look at the features I saw that it lacks acpi so it changes image
HAL table. Is it intentional missing for that os/variant?

[libvirt] [PATCH 0/5] Interface Config public APIs and remote stubs
by Laine Stump
These 5 patches contain the public virInterface*() API definition, the
local plumbing, and the RPC glue. The test driver and real driver are
still TBI, but having this in will allow other people to work on related
stuff.
Other things still needed:
python/java bindings
cli commands in virsh
I'm sure lots of other things I don't know about yet.
Note that I have added a couple things to the API that I previously
didn't realize were needed (virInterfaceRef and virInterfaceFree - I
had figured the client side would just pass around a cookie, not
actually have storage associated with it).

[libvirt] PATCH: Fix virsh reporting open errors
by Daniel P. Berrange
The error handling refactor we did in virsh a few months back, accidentally
means we never report the real libvirt error message for the initial
connection attempt. This patch fixes it
