Re: [libvirt] [PATCH] Add migration APIs for libxl driver



2012/3/15 Jim Fehlig <jfehlig suse com>

While testing this patch, I noticed some strange problems wrt concurrent
operations in the driver.  E.g. if I start a migration and then query
dominfo on the migrating domain, it kills the migration

xen134: # virsh migrate --live sles11sp1-pv xen+ssh://xen142
error: internal error Failed to save domain '7' with libxenlight

Strange. Found that doing whatever operation that needs to open a connect to the hypervisor (even "virsh version") will cause the same issue to live migration. While trying operation that calls do_open the connect, xc_shadow_control( in xc_domain_save) will fail.
Non-live migration is OK.


Thanks!
Jim
