If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an
invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.:
my kernel is 3.2.x which comes with Wheezy as default kernel.i found this
error in many places that this is a kernel bug and shall be fix if i patch
or update the kernel.
So my KVM host is not a production server so i thought it is a best time to
play with the kernal patching because i am working on linux for years but
never perform such task i always rely on default/stable debian repository
but this is a first time i am doing some thing out of the box for fixing
and learning purpose both
so that's the whole story. if you have any other suggestion please share.
Thanks,
I don't know about this specific error, but if you want to try a newer
kernel for Wheezy may I suggest starting with the Debian backport [1]
kernel ? It's a lot easier and less error prone, plus you won't have to
recompile the kernel every time a new kernel comes out to get the fixes.
