Historically the use of the '-desc' multiple argument parameter was not
forbidden toghether with '-edit', but use of both together has some
unexpected behaviour. Specifically the editor is filled with the
contents passed via '-desc' but if the user doesn't change the text in
any way virsh will claim that the description was not chaged even if it
differs from the currently set description. Similarly, when the user
would edit the description provided via 'desc' so that it's identical
with the one configured for the domain, virsh would claim that it was
updated:
# virsh desc cd
No description for domain: cd
# EDITOR=true virsh desc cd --edit "test desc"
Domain description not changed
After the fix:
# virsh desc cd
No description for domain: cd
# EDITOR=true virsh desc cd --edit "test desc"
Domain description updated successfully
# EDITOR=true virsh desc cd --edit "test desc"
Domain description not changed

Non-shared storage migration of guests which are disk I/O intensive and
have fast local storage may actually never converge if the guest happens
to dirty the disk faster than it can be copied.
This patch introduces a new flag
'VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES' which will instruct
hypervisors to synchronize local I/O writes with the writes to remote
storage used for migration so that the guest can't overwhelm the
migration. This comes at a cost of decreased local I/O performance for
guests which behave well on average.

Some of our really old APIs are missing @flags argument. We
introduced their variants with "Flags" suffix and wired some
logic into virsh to call the new variant only if necessary. This
enables virsh to talk to older daemon which may be lacking new
APIs.
However, in case of cmdSetmem() we are talking about v0.1.1
(virDomainSetMemory()) vs. v0.9.0 (virDomainSetMemoryFlags()) and
in case of cmdSetmaxmem() we are talking about v0.0.3
(virDomainSetMaxMemory()) vs v0.9.0 (virDomainSetMemoryFlags()).
Libvirt v0.9.0 was released more than 10 years ago and recently
we dropped support for RHEL-7 which has v4.5.0 (released ~3 years
ago). Thus it is not really necessary to have support in virsh
for such old daemons.
