[pve-devel] [PATCH] phase2_cleanup is phase2 error

But, currently they are no $self->{errors} = 1 in phase2, only die when something bad happen.

also eval_int handle signal interrupt, so I can call phase2_cleanup is task is stopped.

so I think it's more clean to implemented that in AbstractMigrate.

I don't know why you want to change PVE/AbstractMigrate.pm? 
The code set an error flag ($self->{errors} = 1), so you should be able 
to handle those cases inside PVE/QemuMigrate.pm?
