dumping guest's memroy is introduced without compression supported, and this is
a freature regression of 'virsh dump --memory-only'. This patchset is used to
add support in libvirt side to make qemu dump guest's memory in kdump-compressed
format and please refer the following address to see
This patch is used to add dump_memory_format to qemu.conf and libvirt will use
it to specify the default format in which qemu dumps guest's memory. But when
--compress is specified with virsh dump --memory-only, the format configured
by dump_memory_format will be overrided. dump_memory_format can
This patch makes use of the QEMU guest agent to implement the
virDomainMemoryDump API.

Libvirt uses a domain name to fill in owner_name in sanlock_options in
virLockManagerSanlockAcquire. Unfortunately, owner_name is limited to
SANLK_NAME_LEN characters (including trailing '\0'), which means domains
with longer names fail to start when sanlock is enabled. However, we can
truncate

We have to explicitly destroy TAP devices on FreeBSD because
they're not freed after being closed, otherwise we end up with
orphaned TAP devices after destroying a domain.

Added a new test instead of extending an existing one because

Running 'make -C tests check TESTS=qemuagenttest' left a directory
