[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> 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.
