RE: [Xen-users] Fail to create hvm domain

[Sven Oehme <oehmes@xxxxxxxxxx>]

ok, 

here a step by step guide :-)

install FC5 , no xen package now clone
the xen-unstable repro :

hg clone http://xenbits.xensource.com/xen-unstable.hg

cd xen-unstable/buildconfigs

overwrite the linux-defconfig_xen0_x86_32
and linux-defconfig_xen_x86_32 file with the file attached 

now cd back to the xen-unstable directory

and execute make install 

it will ask you some questions for the
kernel config , just press enter here (it will be around 10 times) 

now it should take some time and it
compiles the hypervisor, + the new dom0 kernel and install it into /boot
+ some libs, tools,etc ..

now add the following lines to your
/boot/grub/menu.lst:

title Fedora Core (xen-unstable)
        root (hd0,0)
        kernel /xen.gz
dom0_mem=300M
        module /vmlinuz-2.6.16.13-xen
ro root=/dev/rootvg/rootlv 
        module /initrd-2.6.16.13-xen

now build your initrd with the following
command :  mkinitrd  /boot/initrd-2.6.16.13-xen 2.6.16.13-xen

last step , reboot and choose your new
xen-unstable menu entry ...

after reboot start xend with : /etc/init.d/xend
restart    

create your config for your domains
,etc ....

Thanks, Sven.  I'm trying to follow your advice
and compile from source
obtained from Mercurial.  By following the instructions in the Xen
documentation I can compile fine, but dom0 won't boot.  I suspect
I'm having
problems due to packages and/or lack of an initrd.  I don't have any
experience with kernel compiling or initrd images.  Could you explain
any
more how you did this?  For example, what is the "FC5 config
from the Xen
Kernel?"  And does it create a ramdisk for booting?

Thanks for any clues,

 - Steve

Hi , 

i tried to setup a HVM Domain with the FC5 packages, and failed with all
of
them , even xen-3.0.2-4  from the development repro doesn't work.
i check out the current xen3-unstable from the repository and used my FC5
config from the Xen Kernel to compile packages for FC5 , since then i am
able to create the HVM domains. At least Windows XP works, Vista fails
to
boot ...

[Xen-users] Fail to create hvm domain

                




I'm using FC5 with its Xen 3.0.2-2 package and 2.6.16-1.2118_FC5xen0 kernel.
I've got a Pentium 9xx chip with virtualization enabled in the BIOS; it
appears to be VT-enabled, since xm dmesg includes "(XEN) VMXON is
done".  I
base my config file on example.hvm and on previous emails to this list.
Unfortunately, I don't get very far.  

xm create winxp.conf
Error: (22, 'Invalid argument')

xend-debug.log gives me this:
ERROR: do_evtchn_op: HYPERVISOR_event_channel_op failed: -1

And xend.log spews out all of the stuff below my sig.  I've googled
around
and not found any obvious answers.  Can anyone tell me where to start
looking to fix this?

Thanks,

Steve Brueckner, ATC-NY
