hypervisor - acpi - reboot

hypervisor - acpi - reboot

[Claus Rosenberger]

Hello,

i have several trouble with a MSI X58 Platform with i7 Quadcore and the Xen-4.0.0/Xen-4.0.1-rc4
hypervisor. I'm not able to reboot the machine, it freezes on shutdown, i tried several boot
configurations as listed here.


Reboot doesn't work
-------------------
title           Xen 4.0-amd64 / Debian GNU/Linux, kernel 2.6.32-bpo.5-xen-amd64
root            (hd0,1)
kernel          /xen-4.0-amd64.gz dom0_mem=256M
module          /vmlinuz-2.6.32-bpo.5-xen-amd64 root=/dev/md0 ro console=tty0
module          /initrd.img-2.6.32-bpo.5-xen-amd64


Reboot works
------------
title           Xen 4.0-amd64 / Debian GNU/Linux, kernel 2.6.32-bpo.5-xen-amd64
root            (hd0,1)
kernel          /xen-4.0-amd64.gz dom0_mem=256M acpi=ht noapic noirqbalance
module          /vmlinuz-2.6.32-bpo.5-xen-amd64 root=/dev/md0 ro console=tty0
module          /initrd.img-2.6.32-bpo.5-xen-amd64

title           Debian GNU/Linux, kernel 2.6.32-bpo.5-xen-amd64
root            (hd0,1)
kernel          /vmlinuz-2.6.32-bpo.5-xen-amd64 root=/dev/md0 ro console=tty0
module          /initrd.img-2.6.32-bpo.5-xen-amd64


Rebooting the baremetal dom0 kernel works as expected without any options. I tried one entry more.

title           Xen 4.0-amd64 / Debian GNU/Linux, kernel 2.6.32-bpo.5-xen-amd64
root            (hd0,1)
kernel          /xen-4.0-amd64.gz dom0_mem=256M
module          /vmlinuz-2.6.32-bpo.5-xen-amd64 root=/dev/md0 ro console=tty0 acpi=off
module          /initrd.img-2.6.32-bpo.5-xen-amd64

With this configuration reboot works but the network card has packet loss and outages within several
minutes from time to time.

At lease only one configuration works but without acpi, so the question is why. I'm sorry because i
cannot send some logs, but the internet provider where the server is located is not able to connect
a serial device to save console logs.

Best regards

Claus

Try adding reboot=k to the Xen command line.

That does not work, i tried reboot=b either, does not work too, i used that reference to test
something like that.

Try adding iommu=0 to the Xen command line.

I found one extra link how to test more stuff

I don't know how much it helps to know which of the options does work and which not.

This looks to be the same issue or something like that, i use an i7 Core too

It might be related to pv_ops dom0 kernels then. Perhaps try a non pv_ops
kernel such as the 2.6.32 kernel maintained for the XCP project (patch queue
at http://xenbits.xen.org/XCP/linux-2.6.32.pq.hg).
