Hi, the current problem appears when launching any of the Xen VMS :
First problem (appears all the time when starting a VM) :
4gp seg fixup, process init (pid1), cs:ip 73:002b2b0d
4gp seg fixup, process init (pid1), cs:ip 73:0017fe67
...
Second problem (appears randomly) :
BUG: at kernel/lockdep.c:1858 trace_hardirqs_on()

Third problem (appears randomly when launching machine) :
Kernel panic - not syncing: Attempted to kill init!

Kernel panic - not syncing: Attempted to kill init!
Messages sometimes don't appear in the same order.
If anyone has any help on this :
1 times on 4, the VM started is shut off after the symptomatic Kernel panic.
Sometimes, its starts again (on crash= restart), but sometimes not
The correct "hwcap 0 nosegneg" is set in /etc/ld.so.conf
I am using a single file to store each VM
Using Fedora Core 7 with Xen 3.1 emulated with VMWare Workstation (5.5.2)
without VMWare tools
Thanks in advance
Best regards
