[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] [patch] [xm, xend] passthrough: Add assigned_or_requested_vslot()
Hi Simon,
Great!! Your patch is of importance.
If without your patch, we cannot start domains. I found a problem
about starting domains. The reproduction operations of the problem
are as follows.
Step to Reproduce:
1. xm start <domain>
2. xm pci-attach <domain> **:**.* *
3. Shutdown guest OS on <domain>
4. xm start <domain> ---> fail
Your patch has solved the problem.
Trivial comment:
The following line includes Tab indent.
