[Xen-devel] [PATCH] xend: Receive error message of migration from destination server
Hi,
The following error message was shown by xm migrate command.
In fact, I caused the command error by intention. I prepared a
destination server where free memory was insufficient, and then
I tried to migrate a VM to the destination server. As I had
expected, the command error occurred. However the error message
was different from my expectation. I would like to show an error
message from the destination server if an error occurred on the
destination server.
# xm migrate --live vm3 bx339
Error: (107, ''Transport endpoint is not connected'')
Usage: xm migrate <Domain> <Host>
Migrate a domain to another machine.
Options:
-h, --help Print this help.
-l, --live Use live migration.
-p=portnum, --port=portnum
Use specified port for migration.
-n=nodenum, --node=nodenum
Use specified NUMA node on target.
-s, --ssl Use ssl connection for migration.
If a destination server sends an error message, this patch shows
the error message. For example, the following error message is
shown if free memory of the destination server is insufficient.
# xm migrate --live vm3 bx339
Error: I need 262144 KiB, but dom0_min_mem is 716800 and shrinking to
716800 KiB would leave only 50368 KiB free. (from bx339)
Usage: xm migrate <Domain> <Host>

-p=portnum, --port=portnum
