Xen users - Feb 2006 - Hypervisor crashes while restoring saved domU

Hello,

I have problems with restoring Xen''s saved domU.

my OS and hardware configuration is:
  - Debian Sarge 64 bit with 2 x Opteron
  - 8 GB RAM
  - LVM + 3ware 9550

and Xen 3.0.1 compiled from sources.

When I''m trying to restore saved domain (Debian too - on 2.6.12) I 
hypervisor crashes...

I have tried to search in mailing list archives, but found nothing 
similiar. Did anyone meet something like that below?

Cheers,
Adam

help

 

 

Hi, I''m working with Xen 3.0.1 and I have the following problem:

 

I''m running Xen in a VT enabled Intel processor, I have successful
installed a Fedora Core 4 32 bits Guest using VT. But the 

Network interface doesn''t appear in the Guest. I mean, running the
commands "ifconfig -a" doesn''t show any eth0 interface just
lo.

In the /sys/class/net directory there is not any ethX interface and
neither in the dmesg log appears nothing about eth0.

Finally when I run the command: lspci -v, there are the following
devices:

 

Host bridge: Intel Corporation 440FX

ISA bridge: Intel Corporation 82371SB

IDE interface: Intel Corporation 82371SB

VGA compatible controller: Cirrus Logic GD

 

And anything about a Network interface.

 

What can I do?, running a Linux Paravirtualized Guest (xenU) shows the
interface eth0 without any problem.

 

I adjusted the .config file for the xen0 domain. I added EHCI support
and USB mass storage, and also support for SMP machines.

I did it using the following command:

 

In the xen directory:

 

 

make linux-2.6-xen0-config CONFIGMODE=menuconfig

make linux-2.6-xen0-build

make linux-2.6-xen0-install

 

And reboot. 

 

What options are needed in the .config file for Xen0 in order to create
the virtual network devices in the VMX guests?

 

Thanks

 

Jesus
