I will refer to this TEST1

I will refer to this TEST2

Yes XenDemoCD 1.0 (TEST2) boot is o.k. no more tests done.
If it make sense I will test domain starting, ssh
...

More Info about 5 CPUs:
1. Only "server1" has 5 CPUs (TEST1 1 CPU
o.k., 2CPUs fail, 5CPUs fail)
2. TEST2 was on "server2" (4 CPUs)

With 2 CPUs fail.

Output when it fails:
    megaraid scanning raidchannel with error:
      scsi0: scanning virtual channel0
for scsi devices.
      scsi_wait_req: still waiting...!
      scsi_wait_req: still waiting...!
      scsi_wait_req: still waiting...!
      (... endless)

Helpful info from a previous TESTx:
    BIOS AIC-7880 enabled + Netraid (megaraid)
enabled
    Bootsequence 1. AIC-7880, 2. Netraid

    Output when it fails:
      ... "adaptec scanning"
... (this text is not copy/paste)
      scsi_wait_req: still waiting...!
      scsi_wait_req: still waiting...!
      scsi_wait_req: still waiting...!
      (... endless)

very good :-)
