[libvirt] [PATCH v2 0/2]impl separite module for hostdev passthrough
by Chunyan Liu
This patch series include two patches:
1/2 is the implementation of the hostdev passthrough common library.
To meet two purposes:
a. move qemu hostdev APIs to common library so that it could be used by all
hypervisor drivers.
b. maintain a global hostdev in-use state.
2/2 is the implementation of pci passthrough to libxl driver.
Using common library APIs to implement pci passthrough for libxl driver.
(Changes to qemu/lxc driver are not included yet. That could be done after common
library is confirmed.)
Changes to v1:
1/2:
* add scsi part to common library
* instead of hardcode, check for <driver name='kvm/vfio/xen'/> setting, call
virPCIDeviceSetStubDriver to set stub driver. For libxl driver, a <driver
name='xen' /> is needed.
* rebase to current libvirt changes
2/2:
* Add device-attach/detach a pci hostdev implementataion to libxl driver
Chunyan Liu (2):
add hostdev passthrough common library
add pci passthrough impl to libxl

Just a minor nit which lets Emacs' nxml-mode fail when parsing

[libvirt] [PATCH] nodedev: fix vport detection for FC HBA
by Ján Tomko
Use the host number as the host number when constructing the sysfs path
instead of the variable we are trying to fill.

Untested, but we do the same in virFindFCHostCapableVport
in src/util/virutil.c.

[libvirt] Can we allow users in 'qemu' group to skip polkit auth?
by Cole Robinson
There's a bug report filed against Fedora libvirt requesting a polkit rule be
installed that grants read/write libvirt access to all users in the 'qemu' group:
https://bugzilla.redhat.com/show_bug.cgi?id=957300
I'm inclined to agree with the reporter, and time has shown that many users
install custom polkit rules to grant their user passwordless access to libvirt
so this would definitely fill a need.
I'm sure there's plenty to consider here since we are talking about security.
Thoughts?
Thanks,
Cole

[libvirt] Disabling bootmenu causes boot to skip over cdrom
by Keno Fischer
Hello,
I have domain with the following setup:
- 1 VirtIO Disk
- 1 VirtIO CDROM
- 2 IDE CDROMs
Now, depending on whether or not I have the bootmenu flag enabled, the boot
sequence skips over booting from CDROM entirely (it does work if the
bootmenu is enabled).
This started happening after I added the VirtIO CDROM. Is this a bug or am
I doing something wrong?
Thanks,
Keno Fischer

[libvirt] [PATCH] doc: Explicitly document migration limitations on errors
by Peter Krempa
Migration of guests that are in error state for example because of I/O
errors may not be possible and encountering of such errors may lead to
cancellation of such migration. Document this behavior explicitly.
