[Xen-users] Blank screen kernel 2.6.33 Xen 3.4.2
Hello, I''m experimenting with Debian Testing 64bit, vanilla kernel
2.6.33 and xen 3.4.2 from sources on a Dell Poweredge r210 with 2 sata
disk in raid1.
I''m not an expert, before this try I''ve used only Xen in
Debian 5 from
the packages provided by Debian.
From what I''ve understand with kernel 2.6.33 compiled with:
CONFIG_XEN=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=32
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_FBDEV_FRONTEND=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
I can use the same kernel for dom0 and domu. I''ve recompiled the kernel
and the sistem boots without trobule. The problems starts when I want to
boot the system with the hypervisor.
In grub2 I have this entry:
menuentry "Xen 3.4.2 2.6.33" {
set root=(md0)
echo Loading Linux 2.6.33 Xen 3.4.2
multiboot //xen.gz
module //vmlinuz-2.6.33-custom root=/dev/md1 ro console=tty0
}
When I boot from this entry I can see messages from Xen (it recognizes
the four Xeon core installed on the system) but after 2 seconds the
screen blanks. I cannot see any error, the screen is too fast and I
cannot pause it.
These are my partitions:
/dev/md1 on / type ext4 (rw,noatime,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/md0 on /boot type ext3 (rw)
/dev/mapper/vmimages-vmimages on /srv type ext4 (rw,noatime)
How can I debug this? Thanks for the support.
