I posted 'xm save --checkpoint' problem in the past.
just snapshot with 'xm save' works well.
but live checkpoint 'xm save --checkpoint' command doesn't work well.
As you know, '-c' option means "leaving domain running after creating
snapshot"
but after checkpointing, domU state is bad
xm console [domain] after checkpointing,
WARNING: g.e. still in use!
WARNING: g.e. still in use!
WARNING: g.e. still in use!
WARNING: g.e. still in use!
domU login prompt following this message appeared.
And, I try to login my guest domU, domU does not show any responses.
after destroy domU, I try to restore by snapshoted file and it seems to work
well.
I have tested xen 3.4.2 with pvops 2.6.31.6,
and now, xen-unstable 4.1 with pvops 2.6.32.15 also have same problem
my disribution is ubuntu 9.10 karmic server
I snapshoted the guest disk image (lvm) by applying following scripts
