Re: [Xen-ia64-devel] [IPF-xenU] "xm destroy" xenU may make xen0 crash

[Doi.Tsunehisa@xxxxxxxxxxxxxx]

Hi,

  It's a temporary solution to avoid hypervisor crash...

  We can avoid to crash hypervisor with `xm network-detach' command.
Before the domain destruction, you should detach all VNIF of the domain
with `xm network-detach <domid> <nifid>' command, if you want to avoid
crash hypervisor.

Thanks,
