[libvirt] Segfault in virCommandRun when trying to start a QEMU guest
by Matthias Bolte
In qemudStartVMDaemon in/out/err for the virCommand are set based on
FDs this results in a segfault in virCommandRun here
VIR_DEBUG("Result stdout: '%s' stderr: '%s'",
NULLSTR(*cmd->outbuf),
NULLSTR(*cmd->errbuf));
as cmd->outbuf and cmd->errbuf are NULL.
The two if blocks before that setup cmd->outbuf and cmd->errbuf in
case the caller didn't request output capturing aren't executed
because the caller requested to capture the output to FDs.
/* If caller hasn't requested capture of stdout/err, then capture
* it ourselves so we can log it.
*/
if (!cmd->outfdptr) {
cmd->outfdptr = &cmd->outfd;
cmd->outbuf = &outbuf;
}
if (!cmd->errfdptr) {
cmd->errfdptr = &cmd->errfd;
cmd->errbuf = &errbuf;
}
In the case the caller requested to capture the output to FDs there is
no capturing to cmd->outbuf and cmd->errbuf and they stay NULL.
When I remove that offending VIR_DEBUG line everything works fine.
Also this case of FD only usage is not yet covered in the command API
test cases.

[libvirt] [PATCH] Create file in virFileWriteStr() if it doesn't exist
by Jean-Baptiste Rouault
This patch adds a virFileWriteStrEx() function with a
third parameter to set the created file permissions.
virFileWriteStr() calls this new function with a
default value for the mode parameter.

[libvirt] [PATCH 0/2] smbios fixes
by Eric Blake
In testing <smbios mode='host'/>, I noticed a couple of problems.
First, qemu rejected the command line we gave it (invalid UUID);
ifixingthat showed that all other arguments were being given literal
"" which then made the guest smbios differ from the host. Second,
the qemu option -smbios type=1,family=string wasn't supported, which
lead to a spurious difference between host and guest.
Meanwhile, qemu has a bug where '-smbios type=1,uuid=uuid' must parse
as a valid uuid, but is otherwise ignored. The current qemu.git code
base _only_ sets smbios uuid from the '-uuid uuid' argument. I've
filed a bug against the qemu folks asking whether this is intended (in
which case we have to modify libvirt to change the -uuid argument it
outputs when smbios is specified), or an oversight (hopefully the
latter, since it's still nice to correlate
/var/log/libvirt/qemu/....log with the XML uuid even when that differs
from the smbios uuid presented to the guest.)

smbios: support system family

[libvirt] [PATCH] virsh: Remove redundant optional option for cmdHelp
by Osier Yang
Remove the optional option "group", as cmdHelp should accepts
only one option, and rename option "command" as "command-or-group",
("virsh help" supports both command and command group now, and user
nealy uses the options, so it doesn't matter much for it being longer,
:-)

[libvirt] [PATCH v5 0/4] Support of auto-dump on watchdog event in libvirtd
by Hu Tao
This patch series adds a new watchdog action `dump' which lets libvirtd
can do auto-dump when receiving a watchdog event from qemu guest.
In order to make the function work, there must be a watchdog device
added to guest, and guest must have a watchdog daemon running, for
example, /etc/init.d/watchdog start or auto-started on boot.
Changes:
v5:
- qemu_driver is passed into threadpool as opaque parameter rather than
visit the global qemu_driver in worker function
- same situation as above of server in libvirtd.c
- also list auto_dump_path in src/qemu/libvirtd_qemu.aug and
src/qemu/test_libvirtd_qemu.aug
- check return value of qemuDomainObjEndJob for safety
v4:
- updated threadpool to follow libvirt naming style, use appropriate
internals APIs, and hide the struct definitions from the header
(by Daniel)
- fix an error that qemuDomainObjBeginJobWithDriver() get lost in
qemuDomainCoreDump()
- use thread pool in libvirtd (qemud worker)
v3:
- let default auto-dump dir be /var/lib/libvirt/qemu/dump
Hu Tao (4):
threadpool impl
Add a new function doCoreDump
Add a watchdog action `dump'
Using threadpool API to manage qemud worker
