Changes from v1: - Add volume support for the bhyveload command as well to allow booting from a volume Changes from v2: - Move disk source pool translation to storage/storage_driver.c instead of conf/domain_conf.c, because having that in conf/domain_conf.c requires pulling storage driver that is not needed for many drivers Roman Bogorodskiy (2): conf: make disk source pool translation generic bhyve: add volumes support src/bhyve/bhyve_command.c | 17 ++- src/bhyve/bhyve_command.h | 7 +- src/bhyve/bhyve_driver.c | 4 +- src/bhyve/bhyve_process.c | 4 +- src/qemu/qemu_conf.c | 243 ------------------------------------------ src/qemu/qemu_conf.h | 3 - src/qemu/qemu_driver.c | 6 +- src/qemu/qemu_hotplug.c | 3 +- src/qemu/qemu_process.c | 5 +- src/storage/storage_driver.c | 245 +++++++++++++++++++++++++++++++++++++++++++ src/storage/storage_driver.h | 4 + tests/Makefile.am | 3 + tests/bhyvexml2argvtest.c | 5 +- tests/qemuxml2argvtest.c | 3 +- 14 files changed, 287 insertions(+), 265 deletions(-) -- 1.9.0

[libvirt] [RFC] Introduce API for retrieving bulk domain stats
by Peter Krempa 19 Aug '14

19 Aug '14

I'd like to propose a (hopefully) fairly future-proof API to retrieve various statistics for domains. The motivation is that management layers that use libvirt usually poll libvirt for statistics using various split up APIs we currently provide. To get all the necessary stuff, the mgmt app need to issue Ndomains * Napis calls and cope with the various returned formats. The APIs I'm wanting to introduce here will: 1) Return data in a format that we can expand in the future and is hierarchical. For starters I'll use XML, with possible expansion to something like JSON if it will be favourable for a consumer (switchable by a flag) 2) Stats for multiple (all) domains can be queried at once and are returned in one call. This will allow to decrease the overhead necessary to issue multiple calls per domain multiplied by the count of domains. 3) Selectable (bit mask) fields in the returned format. This will allow to retrieve only specific stats according to the APPs need. The returned XML will have the following format: <domainstats> <domain name='vm1'> <state>running</state> <cpus> <cpu id='1'> <state>running</state> <time>10001231231</time> </cpu> <cpu id='2'> <state>offline</state> <time>10001231231</time> <cpu> </cpus> ... </domain> <domain name='vm2'> <state>paused</state> ... </domain> <domain name='vm3'> <state>running</state> ... </domain> </domainstats> Initially the implementation will introduce the option to retrieve block, interface and cpu stats with the possibility to add more in the future. The stats groups will be enabled using a bit field @stats passed as the function argument. A few groups for inspiration: VIR_DOMAIN_STATS_CPU VIR_DOMAIN_STATS_BLOCK VIR_DOMAIN_STATS_INTERFACE As this is a first draft and dump of my mind on this subject it may be a bit rough, so suggestions are welcome. Thanks for looking.

[libvirt] [libvirt-glib] [PATCH 0/4] Add more snapshot API
by mail＠baedert.org 19 Aug '14

19 Aug '14

From: Timm Bäder <mail(a)baedert.org> The following 4 patches add some more snapshot API to libvirt-glib. I wasn't sure where to put _revert_to really, the libvirt API sounds like it belongs into GVirDomain (i.e. gvir_domain_revert_to_snapshot), but virDomainRevertToSnapshot only takes a pointer to the snapshot. The implementation of gvir_domain_snapshot_set_config does not allow renaming of the snapshot as that will just create a new snapshot in any case (should that by documented?). But it looks like the same is true for gvir_domain_set_config?

[libvirt] [RFC] powerpc : Add support for VM in compat mode
by Prerna Saxena 19 Aug '14

19 Aug '14

PowerISA allows processors to run VMs in binary compatibility ("compat") mode supporting an older version of ISA. Eg,in compatibility mode, a POWER8 host can run a "Power7" VM,conforming to PowerISA v2.06, while a POWER7 host can run a "POWER6" VM, conforming to PowerISA v2.05. QEMU has recently added support to explicitly denote a VM running in compatibility mode through commit 6d9412ea. Now, a "compat" mode VM can be run by invoking this qemu commandline on a POWER8 host: -cpu host,compat=power7 as against the older specification of "-cpu power7". However, running in compatibility mode is not identical to running natively on an older processor. Hence the virtualization stack needs to explicitly provide for a compat-mode VM. This patch allows libvirt to extend the "fallback" semantics of cpu model to describe this new mode for PowerKVM guests. Additionally with the new scheme of things, qemu doesn't provide a way to query for the supported compat models and models returned when querying with '-cpu ?' are no longer valid. Hence removing the check cpuModelIsAllowed() for now. When a user wants to request a power7 vm to run in compatibility mode on a Power8 host, this can be described in XML as follows : <cpu mode='custom' match='exact'> <model fallback='compat'>power7</model> </cpu> An alternative approach could be to leave the libvirt XML intact, and merely change the backend qemu command generation when the VM-requested cpu does not match the host processor.
