Is MSI-X can't be enabled or the device only have MSI capability? Just 
curious...

Didn't see exception in the log below... (And buried with iscsi log I can't 
understand. Looking forward for the help from others...) Any thing notable 
show in the host side? I think the target to get pSCSI work well now?

BTW: Maybe you can try the patch from Marcelo titled "[patch 0/4] use 
smp_send_reschedule in vcpu_kick / assigned dev host intx race fix".
