[libvirt] PATCH: Add --tree flag to virsh nodedev-list
by Daniel P. Berrange
The virsh noddev-list command is used to display node devices. It just
prints out their names in a flat list. When detaching devices for purposes
of PCI passthrough though, it is important to understand what devices are
children of the PCI device about to be detached. It is tedious to find
this out, the user having to run virsh nodedev-dumpxml and look at the
parent field.

[libvirt] question about qemudDomainMigratePrepare2 of qemu_driver.c from libvirt-0.6.1
by Gerrit.Slomma＠drv-bund.de
Hello
I am just curious if the checking of the connection string in qemu_driver.c
from libvirt-0.6.1 in qemudDomainMigratePrepare2 is faulty.
The source is:
[...]
} else {
/* Check the URI starts with "tcp:". We will escape the
* URI when passing it to the qemu monitor, so bad
* characters in hostname part don't matter.
*/
if (!STREQLEN (uri_in, "tcp:", 6)) {
qemudReportError (dconn, NULL, NULL, VIR_ERR_INVALID_ARG,
"%s", _("only tcp URIs are supported for KVM
migrations"));
goto cleanup;
}
[...]
The second compare-string "tcp:" is only 4 characters long, therefore a
check via strncmp must fail i presumed, i isolated this comparison:
#include <stdio.h>
#include <string.h>
#define STREQLEN(a,b,n) (strncmp((a),(b),(n)) == 0)
int main ()
{
char str[][200] = { "tcp://192.168.1.14:4444" , "tcp:192.168.1.14:4444" ,
"ssh
://192.168.1.14:4444" , "ssh:192.168.1.14:4444" };
int n;
for (n=0 ; n<4 ; n++)
{
printf("testing %s against \"tcp:\" with result: ", str[n]);
if (!STREQLEN(str[n],"tcp:",6))
{
printf ("ERROR\n");
}
else
{
printf ("OK\n");
}
}
return 0;
}
and as i pressumed this gives me on the commandline:
testing tcp://192.168.1.14:4444 against "tcp:" with result: ERROR
testing tcp:192.168.1.14:4444 against "tcp:" with result: ERROR
testing ssh://192.168.1.14:4444 against "tcp:" with result: ERROR
testing ssh:192.168.1.14:4444 against "tcp:" with result: ERROR
if i change the 6 to 4 it gives
testing tcp://192.168.1.14:4444 against "tcp:" with result: OK
testing tcp:192.168.1.14:4444 against "tcp:" with result: OK
testing ssh://192.168.1.14:4444 against "tcp:" with result: ERROR
testing ssh:192.168.1.14:4444 against "tcp:" with result: ERROR
but now tcp:// also is marked as correct.
Am i missing something here and the checking in qemu_driver.c is correct?
I always get the "only tcp URIs are supported for KVM migrations" if i try
to migrate KVM-domains in virt-manager 0.7.0 and therefore searched for the
root-cause of this problem.
Kind regards, Gerrit Slomma

[libvirt] PATCH: Fix error reporting for guest with missing network
by Daniel P. Berrange
If you attempt to create a Xen guest using a virutal network that does not
exist, or is not running you get a cryptic message
# virsh create rhel5pv.xml
error: Failed to create domain from rhel5pv.xml
error: XML description for failed to build sexpr is not well formed or invalid
This is because the XenD/XM drivers are both overwriting errors that have
already been reported. The fix is simply to remove this bogus error call.
It also tweaks the original error reporting to be more meaningful.
The result is this
# virsh create rhel5pv.xml
error: Failed to create domain from rhel5pv.xml
error: Network not found: default

[libvirt] PATCH: Fix error report for unknown node devices
by Daniel P. Berrange
When requesting a non-existant device you currently get
# virsh nodedev-dumpxml foo
error: Could not find matching device 'foo'
error: invalid node device pointer in no node device with matching name
This patch fixes that to give
# virsh nodedev-dumpxml foo
error: Could not find matching device 'foo'
error: Node device not found

[libvirt] PATCH: Update XenD for new location of (localtime 1) SEXPR
by Daniel P. Berrange
Newer versions of XenD have the (localtime 1) bit of the SEXPR
moved outside the (image ...) bit, and made available for both PV
and HVM guests. This patch updates our code to cope with this. For
compatability we also still put the (localtime 1) bit inside the
HVM (image ...) section too - its harmless on new XenD, and stops
us breaking old deployments. Finally, this also updates the XM
driver to accept localtime=1 for PV guests.

[libvirt] [Fwd: first cut public API for physical host interface configuration]
by Laine Stump
(Oops, I originally sent this with the wrong return address, which
probably caused it to be silently swallowed...)
To get started integrating libnetcf support into libvirt, the attached
libvirt.h diff has a first attempt at the public API that will hook up
to libnetcf on the libvirtd side. I started out with the virNetwork*
API, and modified/removed as seemed appropriate.
A few points worth mentioning:
virNetwork has "defined" and "active" interfaces, but so far
virInterface just has interfaces, as the active/inactive status is
really controlled by 1) the "onboot" property in the XML, and 2) whether
or not virInterfaceStart() has been called yet.
The _virInterface struct that is referenced here is more or less
identical to _virnetwork.
libnetcf works with netcf structs (one per library instance) and
netcf_if structs (one per interface, multiple per library instance. As
far as I can see right now, the netcf struct will not need to be
referenced directly from the client side, but the netcf_if for each
interface is needed, and I guess a cookie representing it will be sent
to the client side and stored in the _virInterface. Is that what the
UUID in _virNetwork is used for? (I know, I know - "read the code!",
it's just quicker to (and avoids misreading on my part) to ask)
As before, any and all advice/corrections gratefully accepted!
