[Libvir] [PATCH] Add bus attribute to disk target definition
by Soren Hansen
Hi!
I'd like to propose that the following patch gets applied against
libvirt. It adds the option of putting a bus attribute on a disk target.
To acommodate this, it also changes the way drives are defined for kvm
from the old "-hda /path/to/file -boot c" style to the new "-drive
file=/path/to/file,if=ide,boot=on". This makes it possible to specify
virtio, scsi, and ide disks.

[Libvir] [PATCH] Fix USB device name mis-conversion from S-Expr to XML
by Hiroyuki Kaguchi
"tablet" and "mouse" are set as a value of the
/local/domain/<domid>/image/hvm/usbdevice,
but libvirt expects "usbdevice" and "usbmouse" as a value.
This causes the following.
If a USB device is attached by virt-manager,
the USB device is not seen from virt-manager.
This patch fixes expected value of libvirt
Thanks,
Hiroyuki Kaguchi

[Libvir] Reopening the old discussion about virDomainBlockPeek
by Richard W.M. Jones
Virt-df[1] has now gained the ability to fully parse LVM2 partitions,
thus:
# virt-df -c qemu:///system -h
Filesystem Size Used Available Type
rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3
rhel51x32kvm:VolGroup00/LogVol00 6.4 GiB 3.6 GiB 2.8 GiB Linux ext2/3
rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap
However it still has to do it by opening the local partitions / files,
which means it isn't using a "proper" part of libvirt and more
importantly it cannot run remotely.
I'd like to find out whether the time has come for us to look again at
a virDomainBlockPeek call for libvirt. Here is the original thread
plus patch from 7 months ago:
http://www.redhat.com/archives/libvir-list/2007-October/thread.html#00089
(I've attached an updated patch against current CVS).
I appreciate that some cases might not be simple (iSCSI?), but the
same argument applies to block device statistics too, and we make
those available where possible. I think a best-effort call allowing
callers to peek into the block devices of guests would be very useful.
Rich.

[Libvir] KVM migration
by Richard W.M. Jones
It turns out that the general migration strategy I defined[1] in
reference to Xen, ie. the 3 steps of Prepare/Perform/Finish, isn't
sufficient to support KVM migration.
The problem is that the destination needs to start qemu-kvm with
pretty much the exact same configuration / command line parameters as
were used at the source[2]. eg. If the source qemu-kvm has 512 MB of
RAM, then the destination had better have exactly 512 MB of RAM also.
(This is not the same as Xen where the migration protocol itself
carries this information between the two xend daemons).
We can modify the Prepare step to pass this information -- I'm
suggesting that we just pass the domain XML of the source domain.
Thus the Prepare step would change from:
static int
qemudDomainMigratePrepare (virConnectPtr dconn,
char **cookie,
int *cookielen,
const char *uri_in,
char **uri_out,
unsigned long flags,
const char *dname,
unsigned long resource)
to:
static int
qemudDomainMigratePreparev2 (virConnectPtr dconn,
char **cookie,
int *cookielen,
const char *uri_in,
char **uri_out,
+ const char *dom_xml,
unsigned long flags,
const char *dname,
unsigned long resource)
As hinted there, we also need a new version of the migration protocol,
and a new remote call (Preparev2).
So questions:
(a) Does anyone have any objections?
(b) Does anyone see a simpler way to do this?
(c) Since we're adding a second version of the protocol, does anyone
want anything else added?
(d) Will the domain XML alone be sufficient to recreate the exact
qemu command line? (Seems to be the case, and in fact KVM suspend/
restore support seems to implicitly rely on this too).
Rich.

[Libvir] How to get the memory used by a guest domin
by Pranay Prasoon
Hi,
It appears to be no API available to provide the memory used by a guest
domin.
I looked at the availble libvirt api called "virNodeGetCellsFreeMemory"
using which it is possible to get the free mem. But looking further I found
that this is free memory of the "whole box" rather than based upon the guest
domain.
How can I get the memory used by a guest domin.
Thanks n Regards,
-Pranay.

[Libvir] [PATCH] sound support for qemu and xen
by Cole Robinson
The patch below adds xml support for the soundhw option to qemu
and xen. The new xml element takes the form:
<sound driver='drivername'/>
Where driver name can be pcspk, sb16, es1370, or all.
Everything seems to be in working order but I have a few
implementation questions:
1) Should multiple drivers be able to be specified? qemu
accommodates this, allowing '-soundhw sb16,pcspk' for example.
If this should be allowed, what should the xml format be?
2) Should acceptable driver options be hardcoded? The other option
is to just pass the input straight to qemu. This patch has the
options hardcoded.
Also I realize this will probably need to be rediff'd around
Dan's serial + parallel device patch, but I figured I would just
get this out there.
Thanks,
Cole

[Libvir] [PATCH][RFC] libvirt ldoms support
by Ryan Scott
Note: I haven't tried building this on Linux yet, so we may have some
#ifdef or Makefile changes on non-Solaris platforms.
Please Cc: Eunice.Moon(a)Sun.COM on any response.
Thanks,
Ryan
LDoms Support
This patch adds the Logical Domains (LDoms) support for the SPARC
platforms. LDoms software is Sun Microsystem's virtualization technology
to subdivide a supported system's resources (CPUs, memory, I/O, and
storage) creating partitions called logical domains. The Logical Domains
Manager is used to create and manage logical domains and maps logical
domains to physical resources. The LDoms Manager provides a command-line
interface and also exports an XML-based control interface. The Libvirt
for LDoms uses this XML interface to communicate with the LDoms Manager
to retrieve the LDoms data for:
- Listing domains
- Requesting CPU and memory resource updates
- Performing life-cycle actions for logical domains
This libvirt patch supports LDoms 1.0.1 and 1.0.2.
This patch will modify the following existing files:
src/libvirt.c
src/virsh.c
src/virterror.c
src/driver.h
src/Makefile.am
include/libvirt/libvirt.h.in
include/libvirt/virterror.h
configure.in
and add the following new files:
src/ldoms_common.h
src/ldoms_internal.h
src/ldoms_internal.c
src/ldoms_intfc.h
src/ldoms_intfc.c
src/ldoms_xml_parse.h
src/ldoms_xml_parse.c

[Libvir] [PATCH] Implement SetVcpus and DomainGetMaxVcpus for qemu
by Cole Robinson
The attached patch fills in two of the vcpu functions for the qemu driver:
virDomainSetVcpus : set the number of vcpus the domain can use
virDomainGetMaxVcpus : max number of vcpus that can be assigned to the domain.
Code change is only in qemu_driver, as the backend stuff was already in place.
I also edited qemudGetMaxVcpus to ignore case when checking the passed OS
type, since it wasn't matching the returned results of qemudDomainGetOSType.
Thanks,
Cole

[Libvir] make syntax-check fails with bzr checkouts
by Soren Hansen
I seem to be completely unable to get make syntax-checks to function
properly with my bzr checkout of libvirt[1]. I've attached the output as
as-is.txt. I tried adding hacking bzr support into vc-list-files (see
vc-list-files-bzr.patch), but that didn't quite seem to do the trick, as
you can see in in vc-list-files-maybe-fixed.log, which is the output
after I patched vc-list-files.
I tried CVS, too, and that also fails (see cvs-syntax-check.log).
Is it only meant to work with git?
