      libvirt: pass a directory path into drivers for embedded usage · 207709a0
      由 Daniel P. Berrangé 提交于 
      The intent here is to allow the virt drivers to be run directly embedded
in an arbitrary process without interfering with libvirtd. To achieve
this they need to store all their configuration & state in a separate
directory tree from the main system or session libvirtd instances.

This can be useful for doing testing of the virt drivers in "make check"
without interfering with the user's own libvirtd instances.

It can also be used for applications using KVM/QEMU as a piece of
infrastructure to build an service, rather than for general purpose
OS hosting. A long standing example is libguestfs, which would prefer
if its temporary VMs did show up in the main libvirtd VM list, because
this confuses apps such as OpenStack Nova. A more recent example would
be Kata which is using KVM as a technology to build containers.

      Drop needless ret variable · 3b4df5d3
      由 Michal Privoznik 提交于 
      In few places we have the following code pattern:

  int ret;
  ... /* @ret is not accessed here */
  ret = f(...);
  return ret;

This pattern can be written less verbose:

  ...
  return f(...);

This patch was generated with following coccinelle spatch:

  @@
  type T;
  constant C;
  expression f;
  identifier ret;
  @@
  -T ret = C;
   ... when != ret
  -ret = f;
  -return ret;
  +return f;

Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

      vz: acquire a pidfile in the driver root directory · 7cefe611
      由 Daniel P. Berrangé 提交于 
      When we allow multiple instances of the driver for the same user
account, using a separate root directory, we need to ensure mutual
exclusion. Use a pidfile to guarantee this.

In privileged libvirtd this ends up locking

   /var/run/libvirt/vz/driver.pid

In unprivileged libvirtd this ends up locking

  /run/user/$UID/libvirt/vz/run/driver.pid

NB, the latter can vary depending on $XDG_RUNTIME_DIR

      snapshot: Add VIR_DOMAIN_SNAPSHOT_CREATE_VALIDATE flag · 95f8e323
      由 Eric Blake 提交于 
      We've been doing a terrible job of performing XML validation in our
various API that parse XML with a corresponding schema (we started
with domains back in commit dd69a14f, v1.2.12, but didn't catch all
domain-related APIs, didn't document the use of the flag, and didn't
cover other XML). New APIs (like checkpoints) should do the validation
unconditionally, but it doesn't hurt to continue retrofitting existing
APIs to at least allow the option.

While there are many APIs that could be improved, this patch focuses
on wiring up a new snapshot XML creation flag through all the
hypervisors that support snapshots, as well as exposing it in 'virsh
snapshot-create'.  For 'virsh snapshot-create-as', we blindly set the
flag without a command-line option, since the XML we create from the
command line should generally always comply (note that validation
might cause failures where it used to succeed, such as if we tighten
the RNG to reject a name of '../\n'); but blindly passing the flag
means we also have to add in fallback code to disable validation if
the server is too old to understand the flag.
