RE: [Xen-devel] DomU stuck on "Sending DHCP request"

["Puthiyaparambil, Aravindh" <aravindh.puthiyaparambil@xxxxxxxxxx>]

I also noticed that when I do an "xm destroy" on the domain sending out
the DHCP request, I get the following error when I do an "xm list". 

Unexpected error: xen.xend.XendProtocol.XendError

Please report to xen-devel@xxxxxxxxxxxxxxxxxxx

Thereafter xm works fine. But it always give me the error on the first
xm command after the "destroy".


I am getting the following output from tcpdump.
