Sorry for the delay. Long was working on a similar problem and we needed

- The on_cpu to set cr0/cr3/cr4 should be in setup_vm.
2) Execute tests on selected vcpu using on_cpu_async so the tests
may use the on_cpu functions without causing an ipi_lock deadlock.
3) Added additional test svm_init_startup_test which inits the vcpu and
restarts with sipi.

Cathy,
Thanks for the patches. It cleans up the code nicely.
But there are some issues with the patch. I was able to bring the L1 guest
with your patch. But when I tried to load L2 guest it crashed. I am
thinking It is mostly due to save/restore part of
r the current
vmcb which is now vmcb02 as we are in nested mode subsequently
vmcb01.control.asid is never set as it should be.
Tested:

kvm self tests

as scsi_remove_device also tries to take host->scan_mutex.
This results in dragging the VM down and sometimes completely.
This patch only allows one remove lun to be issued to a particular
lun while it is an instantiated member of the scsi stack.

fc_rport_identifiers. This insures that a valid scsi_target_id
is assigned to the newly created rport and it can meet the
requirements of fc_user_scan_tgt calling scsi_scan_target.

ingle threaded queue would have to allow
for only a queue of one and no more. Either that or each work item for a
particular lun must have the same memory address so it gets
rejected if it you try to queue a remove to the same lun twice.
Maybe I am not understanding your suggestion correctly.
Thanks,
Cathy

order to implement the work around so that the scsi scan works
indicating FC_PORT_ROLE_FCP_TARGET as a role was necessary due to its
test in fc_scsi_scan_rport. The idea here is to avoid making any changes
to the fc_transport driver which was of some concern.
Thanks,
Cathy
