Subject: no screen output for '-vga vmware' at boot time
Date: Thu, 06 Jan 2011 15:51:34 +0100 [thread overview]
Message-ID: <4D25D6F6.8030705@aixigo.de> (raw)
Hi folks,
Booting Debian Squeeze on the guest I get a line
Loading initrd...
the rest of the boot procedure is omitted. The initrd
message is not scrolled off the screen.
The guest seems to boot, though. Kdm is shown as usual.
If I switch back to /dev/tty1, then I finally see the
last few lines of the lost screen output.
kvm command line:
kvm -m 512 -drive file=/dev/storage/vdpcl006.vda.lv -vnc :0 -usbdevice tablet -vga vmware
Using "-vga cirrus" there is no such problem.
The problem seems to be related to grub2 and changing the
screen size at boot time. I have added these lines to the
grub configuration on the guest:
GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD_LINUX="keep"
If I omit these lines, then the guest boots as usual.
There is also no problem with 1024x768 if I wait 10 seconds
for grub and the screen size change before connecting the
vncviewer. Timing seems an issue here.
Changing the vnc viewer did not help. I tried xvnc4viewer
and the vnc client in virt-manager. xtightvncviewer was no
option, cause it dies on each change of the screen size.
qemu-kvm is version 0.12.5+dfsg-5, as found in Debian.
Kernel is 2.6.37 (host and guest). I could also reproduce
the problem using Debian's distro kernel for Testing.
Any helpful comment would be highly appreciated.
Regards
Harri
