0cd4cd2904 bhyve: Probe grub-bhyve for --cons-dev capability 2014-11-12 09:55:22 +01:00

17722c169c bhyve: Support /domain/bootloader configuration for non-FreeBSD guests.
We still default to bhyveloader(1) if no explicit bootloader
configuration is supplied in the domain.

If the /domain/bootloader looks like grub-bhyve and the user doesn't
supply /domain/bootloader_args, we make an intelligent guess and try
chainloading the first partition on the disk (or a CD if one exists,
under the assumption that for a VM a CD is likely an install source).

Caveat: Assumes the HDD boots from the msdos1 partition. I think this is
a pretty reasonable assumption for a VM. (DrvBhyve with Bhyveload
already assumes that the first disk should be booted.)

I've tested both HDD and CD boot and they seem to work.

c6e9024867 qemu: fix domain startup failing with 'strict' mode in numatune
If the memory mode is specified as 'strict' and with one node, we
get the following error when starting domain.

error: Unable to write to '$cgroup_path/cpuset.mems': Device or resource busy

XML is configured with numatune as follows:
  <numatune>
    <memory mode='strict' nodeset='0'/>
  </numatune>

It's broken by Commit 411cea638f
which moved qemuSetupCgroupForEmulator() before setting cpuset.mems
in qemuSetupCgroupPostInit.

Directory '$cgroup_path/emulator/' is created in qemuSetupCgroupForEmulator.
But '$cgroup_path/emulator/cpuset.mems' it not set and has a default value
(all nodes, such as 0-1). Then we setup '$cgroup_path/cpuset.mems' to the
nodemask (in this case it's '0') in qemuSetupCgroupPostInit. It must fail.

This patch makes '$cgroup_path/emulator/cpuset.mems' is set before
'$cgroup_path/cpuset.mems'. The action is similar with that in
qemuDomainSetNumaParamsLive.

38a0f6df64 qemu: don't setup cpuset.mems if memory mode in numatune is not 'strict'
If the memory mode in numatune is specified as 'preferred' with one node
(such as nodeset='0'), domain's memory is not all in node 0 absolutely.
Assumption that node 0 doesn't have enough memory, memory can be allocated
on node 1 when qemu process startup. Then if we set cpuset.mems to '0',
it may invoke OOM.

Commit 1a7be8c600 changed the former logic of
checking memory mode in virDomainNumatuneGetNodeset. This patch adds the

f9f0f54524 phyp: Fix NULL dereference in phypConnectOpen
Coverity found out that commit cd490086 caused a possible NULL pointer
dereference.  This is due to the fact, that phyp_driver is NULL at the

However, internal_socket is still the local socket that can be
closed, even unconditionally, if we initialize it to -1.

Enabling this to accept the 'unit' in which memory needs to be specified.
This now allows users to specify memory in units of choice, and
lists the same in 'KiB' -- just like other 'memory' elements in XML.

    <numa>

      <cell cpus='4-7' memory='1024' unit='MiB' />

0396394f02 esx: Simplify VI (vSphere) API and VMware product version handling
Store version numbers in this format

version = 1000000 * major + 1000 * minor + micro

produced by virParseVersionString instead of dedicated enums.

Split the complex esxVI_ProductVersion enum into a simpler
esxVI_ProductLine enum and a product version number.

Relax API and product version number checks to accept everything that
is equal or greater than the supported minimum version. VMware ESX
went through 3 major versions and the vSphere API always stayed
backward compatible. This commit assumes that this will also be true
for future VMware ESX versions.

Also reword error messages in esxConnectTo* to say what was expected
and what was found instead (suggested by Richard W.M. Jones).

01b4de2b9f domain_conf: Use virDomainParseMemory more widely
As reviewing patches upstream it occurred to me, that we have two
functions doing nearly the same: virDomainParseMemory which
expects XML in the following format:

  <memory unit='MiB'>1337</memory>

The other function being virDomainHugepagesParseXML expecting the
following format:

  <someElement size='1337' unit='MiB'/>

It wouldn't matter to have two functions handle two different
scenarios like this if we could only not copy code that handles
32bit arches around. So this code merges the common parts into
one by inventing new @units_xpath argument to
virDomainParseMemory which allows overriding the default location
of @unit attribute in XML. With this change both scenarios above
can be parsed with virDomainParseMemory.

af161e99fd Clean up remote driver connection open code
The remote driver has had a long term hack to deal with the fact
that the old Xen driver worked outside libvirtd, but the rest
of the drivers worked inside. So you could have a local hypervisor
driver but everything else go via the remote driver. The Xen driver
long ago moved inside libvirtd, so this hack is no longer needed.
Thus we should open use the remote driver for secondary drivers
if the primary driver is already the remote driver.

1e91174228 PowerPC:Improve PVR handling to fall back to cpu generation.
IBM Power processors differ uniquely across generations (such as power6,
power7, power8). Each generation signifies a new PowerISA version
that exhibits features unique to that generation.
The higher 16 bits of PVR for IBM Power processors encode the CPU
generation, while the CPU chip (sub)version is encoded in lower 16 bits.

For all practical purposes of launching a VM, we care about the
generation which the vCPU will belong to, and not specifically the chip
version. This patch updates the libvirt PVR check to reflect this
relationship. It allows libvirt to select the right CPU generation
in case the exact match for a a specific CPU is not found.
Hence, there will no longer be a need to add each PowerPC CPU model to
cpu_map.xml; just adding entry for the matching ISA generation will
suffice.

It also contains changes to cpu_map.xml since processor generations
as understood by QEMU compat mode go as "power6", "power7" or "power8"

addce06c92 PowerPC : Add support for launching VM in 'compat' mode.
PowerISA allows processors to run VMs in binary compatibility ("compat")
mode supporting an older version of ISA. QEMU has recently added support to
explicitly denote a VM running in compatibility mode through commit 6d9412ea
& 8dfa3a5e85. Now, a "compat" mode VM can be run by invoking this qemu
commandline on a POWER8 host:  -cpu host,compat=power7.

This patch allows libvirt to exploit cpu mode 'host-model' to describe this
new mode for PowerKVM guests. For example, 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='host-model'>
    <model>power7</model>
  </cpu>

c63ef0452b numa: split util/ and conf/ and support non-contiguous nodesets
This is a reaction to Michal's fix [1] for non-NUMA systems that also
splits out conf/ out of util/ because libvirt_util shouldn't require
libvirt_conf if it is the other way around.  This particular use case
worked, but we're trying to avoid it as mentioned [2], many times.

The only functions from virnuma.c that needed numatune_conf were
virDomainNumatuneNodesetIsAvailable() and virNumaSetupMemoryPolicy().
The first one should be in numatune_conf as it works with
virDomainNumatune, the second one just needs nodeset and mode, both of
which can be passed without the need of numatune_conf.

Apart from fixing that, this patch also fixes recently added
code (between commits d2460f85^..5c8515620) that doesn't support
non-contiguous nodesets.  It uses new function
virNumaNodesetIsAvailable(), which doesn't need a stub as it doesn't use
any libnuma functions, to check if every specified nodeset is available.
