Description Qixiang Wan 2011-04-08 10:20:12 UTC 
Description of problem:
While installing RHEL6.1 (i386 or x86_64) as PV DomU over xen hypervisor, the screen can't be displayed entirely in VNC session. Please refer to the attachment for the screenshot, this could be inconvenient for users to play RHEL6.1 PV on xen.


Version-Release number of selected component (if applicable):
host : RHEL5.6 or RHEL5.6 with the lastest xen : xen-3.0.3-127.el5
guest: RHEL6.1-20110406.0

How reproducible:
100%

Steps to Reproduce:
1. download the kernel and ramdisk from latest RHEL6.1 snapshot
$ wget http://download.devel.redhat.com/rel-eng/RHEL6.1-20110406.0/6.1/Server/x86_64/os/isolinux/vmlinuz -O /tmp/vmlinuz
$ wget http://download.devel.redhat.com/rel-eng/RHEL6.1-20110406.0/6.1/Server/x86_64/os/isolinux/initrd.img -O /tmp/initrd.img

2. Boot up RHEL6.1 PV guest.
$ dd if=/dev/zero of=/tmp/test.img bs=512 count=1 seek=$((12*1024*1024))

$ cat rhel61-64pv.cfg
name = "rhel61x64pv"
maxmem = 1024
memory = 1024
vcpus = 1
kernel = "/boot/vmlinuz"
ramdisk = "/boot/initrd.img"
extra = "method=http://download.englab.nay.redhat.com/pub/rhel/rel-eng/RHEL6.1-20110406.0/6.1/Server/x86_64/os"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ 'type=vnc,vncunused=1,keymap=en-us,vnclisten=0.0.0.0' ]
disk = [ "tap:aio:/tmp/test.img,xvda,w" ]
vif = [ "mac=00:00:36:63:25:02,bridge=xenbr0,script=vif-bridge" ]

$ xm create rhel61-64pv.cfg

3. connect to guest via VNC session, step by step until get the GUI installer screen
  
Actual results:
The the screen of RHEL6.1 PV DomU's GUI installer can't be displayed entirely

Expected results:
The screen of RHEL6.1 installer should be displayed entirely

Additional info:
[1] there is no such defect with RHEL6.0
[2] there is no such defect with RHEL6.1 HVM guest 
[3] can reproduce with old RHEL6.1 snapshots like RHEL6.1-20110224.2
[3] '-std-vga' doesn't help with the issue:
$ mv /usr/lib64/xen/bin/qemu-dm /usr/lib64/xen/bin/xen-qemu-dm
$ echo '/usr/lib64/xen/bin/xen-qemu-dm "$@" -std-vga' > /usr/lib64/xen/bin/qemu-dm
$ chmod +x /usr/lib64/xen/bin/qemu-dm
then start guest:
$ ps aux | grep qemu-dm | grep -v grep
root      9173  0.7  0.2  92184  6712 ?        Sl   05:04   0:00 /usr/lib64/xen/bin/xen-qemu-dm -M xenpv -d 212 -domain-name rhel61x64pv -vnc 0.0.0.0:0 -vncunused -k en-us -std-vga

Comment 4 Andrew Jones 2011-04-08 10:38:43 UTC 
How does the screen look with a RHEL 6.0 GA install? How does it look with a
6.0 GA install but with the kernel updated to 6.1-beta? I'm asking because I'm
wondering if it's an Xorg issue.
Comment 5 Paolo Bonzini 2011-04-08 10:41:53 UTC 
It works with RHEL6.0 GA.  Also, -std-vga works.

I'm trying to bisect it on the kernel now.
Comment 6 Paolo Bonzini 2011-04-08 17:32:22 UTC 
It also fails with RHEL6.1 kernel/initrd and RHEL6 install.img, so the component is correct.
Comment 7 Paolo Bonzini 2011-04-11 11:33:35 UTC 
Oops, sorry, Andrew's comment was right.  It _works_ with kernel 2.6.32-130.el6 and RHEL6 (GA) install image.

working X version: xorg-x11-server-1.7.7-26.el6, pixman 0.16.6
failing X version: xorg-x11-server-1.7.7-28.el6, pixman 0.18.4
Comment 8 Paolo Bonzini 2011-04-11 14:39:54 UTC 
Trying the X server inside a RHEL6 installation works.  Also, for both "working" and "failing" installation, the configuration from "xrandr -d :1 -q" is the same:

Screen 0: minimum 800 x 600, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
   800x600         0.0*

This seems to rule out a relationship with bug 638234.

So moving to the next possible culprit, anaconda.

Reopening as TestOnly so that virt-qe tracks it.

Can someone try this updates.img file and see if it solves the problem?

the update image doesn't help on the issue, still get the same screen as the attachment in comment 1 with the updated image:
$ cat test.cfg
...
extra = "updates=http://10.66.8.1/bz694760.img repo=http://download.englab.nay.redhat.com/pub/rhel/rel-eng/RHEL6.1-20110406.0/6.1/Server/i386/os"
...
Comment 15 Paolo Bonzini 2011-04-14 09:46:25 UTC 
Same here, I dropped it into a directory with the RHEL6.1 install.img and product.img, but I don't see any difference.

Here's a revised updates.img.  Please let me know if this one solves the problem you are seeing.

Third time's a charm.  How about this new updates.img?
Comment 20 Paolo Bonzini 2011-04-15 21:13:40 UTC 
Works here, thanks!

Comment 24 Alexander Todorov 2011-04-20 14:54:12 UTC 
Reproduce with snap #4 and virt-manager. Tested and verified with 0420.n.0.
Comment 25 Yuyu Zhou 2011-04-25 02:42:26 UTC 
Also verified this bug on latest RHEL6.1 snapshot(RHL6.1-2011-0420.0).
The screen of the latest RHEL6.1 PV DomU's GUI installer can be displayed entirely for all combinational conditions(32 on 32, 32 on 64 and 64 on 64).
