[libvirt] [PATCH 0/2]
by Claudio Bley
Hi.
I used the rawhide RPMs to take out the DLLs for a test drive on Windows 64bit
the other day.
While trying to read the "screenshot" from the test domain using the
test:///default connection, I only received 5 Bytes of the libvirtLogo.png file.
Looking at the test driver, the condition piqued my interest, but wasn't the
cause of the short read, only a bit odd. See patch #1.
The actual cause was that the file was opened in text mode and the seventh byte
was a 0x1A which triggered EOF on the FD. See patch #2.

From: "Daniel P. Berrange" <berrange(a)redhat.com>
More OOM fixes. These didn't cause crashes, rather invalid XML / cli
arg generation.

[libvirt] [PATCH] Add --disable-securityfs configure option
by Bogdan Purcareata
Securityfs is not enabled on all kernels running libvirt containers.
This patch introduces a configure option that can specify whether
containers should mount securityfs in their rootfs.

[libvirt] How to intercept the VM start event and run the identity check
by Исаев Виталий Анатольевич
Dear developers!
We are working on the project based on Red Hat Enterprise Virtualisation and Red Hat Identity Management. RHEV environment will be deployed in protected internal enterprise network. Now we are developing special admin tools in order to extend functionality of RHEL IdM and we faced with a rather difficult problem... The system should meet the increased demands of informational security, so what we are trying to implement is:
1. Intercept the event of user's VM start on the RHEL Hypervisor;
2. Suspend the VM;
3. Mount VM's disk to Hypervisor (or some other VM, for instance, admin's VM);
4. Check the integrity of the VM's system files (count md5sum etc.)
5. Unmount disk;
6. If verification is passed, start the VM, else - power off and disable VM till the decision of administrator.
Is there any opportunity to implement this within the libvirt API?
Thank you,
Vitaly Isaev,

[libvirt] [PATCH 00/10] Fix multiple OOM problems
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
Running out long ignored OOM injection tests identified a
number of problems. This series fixes those that I have
found so far, but more are to follow.
I'm also rewriting the OOM injection code to make it much,
much, much faster to run.
Daniel P. Berrange (10):
Fix crash on OOM when parsing disk security label
Fix crash on OOM in parsing CPU mask in domain XML
Fix crash if OOM occurs when creating virConnectPtr
Fix crash on OOM in qemuDomainCCWAddressSetCreate()
Fix crash on OOM in qemuAddRBDHost
Fix allocation of arglist in qemuStringToArgvEnv
Fix error checking of qemuParseKeywords return status
Fix missing OOM check in qemuParseCommandLine when splitting strings
Fix reporting of errors in OOM injection code
Don't ignore allocation failure in virCommandAddEnvPassCommon

[libvirt] [PATCH v4 0/7] cpu: add function to get the models for an arch
by Giuseppe Scrivano
This series adds a new API "virConnectGetCPUModelNames" that allows to
retrieve the list of CPU models known by the hypervisor for a specific
architecture.
This new function is mainly needed by virt-manager to not read
directly the cpu_map.xml file (it could also be different when
accessing a remote daemon).
*v4 main changes
- cpuGetModels translates the arch name to the driver name.
- virConnectGetCPUModelNames handles models==NULL, and
- amended all the changes reported for v3
*v3 main changes
- virConnectGetCPUModelNames returns the number of models instead of
0 on success.
- Use VIR_INSERT_ELEMENT instead of VIR_EXPAND_N.
- Fix a potential memory leak in the python bindings.
- Move virsh changes to a separate commit.
- Remove API documentation from libvirt.h.
*v2 main changes
- set a hard limit for the number of CPU models that is possible to
fetch from a remote server.
- Use VIR_EXPAND_N instead of VIR_REALLOC_N.
- s|1.1.2|1.1.3|
Giuseppe Scrivano (7):
libvirt: add new public API virConnectGetCPUModelNames
cpu: add function to get the models for an arch
virConnectGetCPUModelNames: implement the remote protocol
virConnectGetCPUModelNames: add the support for qemu
virConnectGetCPUModelNames: add the support for the test protocol
virsh: add function to get the CPU models for an arch
python: add bindings for virConnectGetCPUModelNames

[libvirt] [PATCHv2 1/2] VMware: Support more than 2 driver backends
by Doug Goldstein
Currently the VMware version check code only supports two types of
VMware backends, Workstation and Player. But in the near future we will
have an additional one so we need to support more. Additionally, we
discover and cache the path to the vmrun binary so we should use that
path when using the cooresponding binary from the VMware VIX SDK.
