[libvirt] [PATCH] Fix build-time pkg-config files in VPATH
by Jiri Denemark
Since libvirt.h was split into several files, it is impossible to
compile anything against a VPATH-built libvirt. In VPATH, only libvirt.h
is in build/include/libvirt while all other libvirt-*.h files are in
source/include/libvirt.

[libvirt] [PATCH] virsh: Fix types for option bandwidth in block*
by Hao Liu
Bandwidth options in blockcommit, blockcopy, blockjob and blockpull
are parsed by vshCommandOptULWrap() and should be shown as a number
type option.
And a typo is fixed.

[libvirt] [PATCH v2 0/8] Post-copy live migration support
by Cristian Klein
Qemu currently implements pre-copy live migration. VM memory pages are
first copied from the source hypervisor to the destination, potentially
multiple times as pages get dirtied during transfer, then VCPU state
is migrated. Unfortunately, if the VM dirties memory faster than the
network bandwidth, then pre-copy cannot finish. `virsh` currently
includes an option to suspend a VM after a timeout, so that migration
may finish, but at the expense of downtime.
A future version of qemu will implement post-copy live migration. The
VCPU state is first migrated to the destination hypervisor, then
memory pages are pulled from the source hypervisor. Post-copy has the
potential to do migration with zero-downtime, despite the VM dirtying
pages fast, with minimum performance impact. On the other hand, one
post-copy is in progress, any network failure would render the VM
unusable, as its memory is partitioned between the source and
destination hypervisor. Therefore, post-copy should only be used when
necessary.
Post-copy migration in qemu will work as follows:
(1) The `x-postcopy-ram` migration capability needs to be set.
(2) Migration is started.
(3) When the user decides so, post-copy migration is activated by
sending the `migrate-start-postcopy` command. Qemu acknowledges by
setting migration status to `postcopy-active`.
v2:
- Fixed formatting
- Set target version to libvirt 1.2.10
- Only use JSON monitor
- Renamed `qemuMigrateStartPostCopy` to `qemuDomainMigrateStartPostCopy`
- Added parameter `flags` to domainMigrateStartPostCopy (currently unused)
- Misc fixes required for `make check`
- Stop perform phase, when post-copy starts
- Wait for post-copy completion in confirm phase, before killing source VM
Implementation note: `qemuMigrationWaitForCompletion` is overloaded. When
called the first time it waits for post-copy to start, when called the
second time it waits for post-copy to complete. I did so to reduce
code duplication, but am not sure this is the best solution.
Cristian Klein (8):
Added public API to enable post-copy migration
Added public API to start post-copy migration
Added low-level API to qemu post-copy migration
Implemented VIR_MIGRATE_POSTCOPY in qemu driver
Added job type VIR_DOMAIN_JOB_PHASE1_COMPLETED
Implemented post-copy migration logic in qemu
Implement virDomainMigrateStartPostCopy in qemu

[libvirt] [PATCH] CVE-2014-7823: dumpxml: security hole with migratable flag
by Eric Blake
Commit 28f8dfd (v1.0.0) introduced a security hole: in at least
the qemu implementation of virDomainGetXMLDesc, the use of the
flag VIR_DOMAIN_XML_MIGRATABLE (which is usable from a read-only
connection) triggers the implicit use of VIR_DOMAIN_XML_SECURE
prior to calling qemuDomainFormatXML. However, the use of
VIR_DOMAIN_XML_SECURE is supposed to be restricted to read-write
clients only. This patch treats the migratable flag as requiring
the same permissions, rather than analyzing what might break if
migratable xml no longer includes secret information.
Fortunately, the information leak is low-risk: all that is gated
by the VIR_DOMAIN_XML_SECURE flag is the VNC connection password;
but VNC passwords are already weak (FIPS forbids their use, and
on a non-FIPS machine, anyone stupid enough to trust a max-8-byte
password sent in plaintext over the network deserves what they
get). SPICE offers better security than VNC, and all other
secrets are properly protected by use of virSecret associations
rather than direct output in domain XML.
* src/remote/remote_protocol.x (REMOTE_PROC_DOMAIN_GET_XML_DESC):
Tighten rules on use of migratable flag.
* src/libvirt-domain.c (virDomainGetXMLDesc): Likewise.
Signed-off-by: Eric Blake <eblake(a)redhat.com>

The libvirt-security list agreed that this did not need an embargo
because it is low-risk; but I'm on the road this week, so while
this patch for master can go in now, I won't complete the backport
to all the affected stable branches (everything since v1.0.0) or
do the Libvirt Security Notice writeup until Monday.

[libvirt] [PATCH 0/3] Libvirt memory & NUMA fixes
by Prerna Saxena
This patch set addresses a bunch of memory & NUMA fixes.
Series Description:
===========
Patch 1/3 : Use consistent data type to represent memory elements in various XML attributes. This ensures all memory elements are always represented as 'unsigned long long'.
Patch 2/3 : This adds a 'unit' attribute alongwith the 'memory' attribute of a NUMA cell. This enables users to easily describe how much memory needs to be allocated to each NUMA cell for a guest domain.
Patch 3/3 : This augments test cases to add the 'unit' tag.

[libvirt] Local qemu migration
by Marc-André Lureau
Hi,
Attempting to migration from session to system qemu fails because of the
following checks in qemuMigrationCookieXMLParse():
if (STREQ(mig->remoteHostname, mig->localHostname)) {
virReportError(VIR_ERR_INTERNAL_ERROR,
_("Attempt to migrate guest to the same host %s"),
mig->remoteHostname);
goto error;
}
....
if (memcmp(mig->remoteHostuuid, mig->localHostuuid, VIR_UUID_BUFLEN) ==
0) {
virReportError(VIR_ERR_INTERNAL_ERROR,
_("Attempt to migrate guest to the same host %s"),
tmp);
goto error;
Is there a technical limitation for this error? If not, could it be
overriden with an additional flag?
cheers

[libvirt] [PATCH] remote: Fix memory leak in remoteConnectGetAllDomainStats
by Peter Krempa
The remote call actually doesn't free the arguments array so we leak
memory in case a domain list is specified. As the remote domain list
array consists only of stolen pointers from the actual domain objects
it's sufficient just to free the array.
