This patch series introduce new API "virDomainBlockResize" to expose
qemu monitor command "block_size", which is for resizing the a block
device while the domain is running.
The prototype for the new API is:
int
virDomainBlockResize (virDomainPtr dom,
const char *path,
unsigned long long size,
unsigned int flags)
* "@path" is the absolute path of the block device, which can be
extraced from domain xml.
* The units for "@size" is kilobytes, which might be not quite properly.
(qemu HMP uses Megabytes as the default units, QMP uses Bytes as the
default units, so it means we need to divice "@size" by 1024 for HMP,
and multiply "@size" by 1024 for QMP. On the other hand, we need to
check the overflowing). Any ideas on this is welcomed.
* "@flags" is unused currently.
