Hello, There where some issues with the previous branch (pvhvm_v14), I've pushed a new one (pvhvm_v16) that fixes the following bugs: * Make sure there are no IPIs in flight while the VM is migrated, having in-flight IPIs is a problem because on resume the event channels are re-initialized, so all pending events are lost, including IPIs. * Reset the clock after migration, this prevent clock drifts when the VM is migrated. * blkfront was not correctly freeing the old event channel port. The following two commits are needed for Xen: f8e8fd56bd7d5675e8331b4ec74bae76c9dbf24e x86/HVM: fix initialization of wallclock time for PVHVM on migration 32c864a35ece2c24a336d183869a546798a4b241 x86/vtsc: update vcpu_time in hvm_set_guest_time With this branch I've been able to successfully local migrate a busy VM 400 times consecutively. As usual, the branch can be found here: http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=shortlog;h=refs/heads/pvhvm_v16 _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
