[libvirt] [PATCH v2] check if console/channel PTY is null before attempting to open
by Shivaprasad G Bhat 03 Jun '15

03 Jun '15

Console/channel devices have their pty devices assigned when the emulator is actually started. If time is spent in guest preparation, someone attempts to open the console/channel, the libvirt crashes in virChrdevLockFilePath(). The patch attempts to fix the crash by adding a check before attempting to open.

[libvirt] [PATCH 0/2] lxc: allow using 802.11 wireless interfaces in LXC domains
by Lubomir Rintel 03 Jun '15

03 Jun '15

Hi, I'm using libvirt-lxc with mac80211_hwsim to construct virtual wireless network for NetworkManager testing. Currently, I have to move the interfaces to the domains manually, as sharing wan 802.11 wireless link with a LXC namespace does not work: <hostdev mode='capabilities' type='net'> <source><interface>wlan0</interface></source> </hostdev> The wireless links can only be associated to namespaces by moving the underlying PHY instead of the network interface. I'm following up with patches that fix the problem for me; please take a look. Thank you Lubo

[libvirt] [PATCH 0/8 v3] parallels: add vz driver
by Maxim Nestratov 03 Jun '15

03 Jun '15

v2-v3 change: * Patch "parallels: set virtType depending on driver name" reworked. Implemented ability to set virtType depending on driver name. v1-v2 change: * Only "parallels: accept vz as a driver uri and name" patch is changed. Fixed ability to connect to 'parallels' driver and deal with 'Paralells' domain virt type. Maxim Nestratov (8): parallels: introduce vz driver constant and string parallels: use newly introduced VIR_DOMAIN_VIRT_VZ parallels: add new guest capabilities assigned to vz driver parallels: accept vz as a driver uri and name parallels: add a new vz connection driver and hypervisor structures parallels: increment the number of connection drivers parallels: recommend to connect to vz:///system when connection fails parallels: set virtType depending on driver name src/conf/domain_conf.c | 19 ++++++++---- src/conf/domain_conf.h | 1 + src/libvirt.c | 2 +- src/parallels/parallels_driver.c | 63 +++++++++++++++++++++++++++++++++++---- src/parallels/parallels_network.c | 3 +- src/parallels/parallels_sdk.c | 6 +++- src/parallels/parallels_storage.c | 3 +- src/parallels/parallels_utils.h | 1 + 8 files changed, 82 insertions(+), 16 deletions(-) -- 2.1.0

[libvirt] [PATCHv2] Always add 'console' matching the 'serial' device
by Ján Tomko 02 Jun '15

02 Jun '15

We have been formatting the first serial device also as a console device, but only if there were no other consoles. If there is a <serial> device present in the XML, but no serial <console>, or if there isn't any <console> at all but the domain definition hasn't gone through a parse->format->parse round-trip, the <console> device would not be formatted. Change the code to always add the stub device for the first serial device.
