[Xen-users] help launching a Centos 5.5 Xen PV guest on an OpenSuse 11.2 Dom0 host ?

i''ve Opensuse 11.2 Xen Dom0,

       lsb_release -dr
               Description:    openSUSE 11.2 (x86_64)
               Release:        11.2

       uname -a
               Linux server 2.6.34-42-xen #1 SMP 2010-06-01 15:17:00
+0200 x86_64
x86_64 x86_64 GNU/Linux


       rpm -qa | grep -i xen
               xen-libs-4.0.0_21087_01-38.1.x86_64
               kernel-xen-devel-2.6.34-42.1.x86_64
               xen-tools-4.0.0_21087_01-38.1.x86_64
               kernel-xen-2.6.34-42.1.x86_64
               xen-4.0.0_21087_01-38.1.x86_64

I build & run numerous OpenSuse DomUs -- no issues.

I need to netinstall a Centos 5.5 PV''d DomU Guest on this host.

Using the procedure & config below, it starts to boot -- then hangs,
with not much useful debugging info ... at least, not to my eye,
where/how I''m looking.

If someone could once-over the following, and make any
suggestions/hints as to what''s up, it''d be appreciated!

Here''s the current step-by-step:

lvcreate -n vm_boot -L 160M /dev/VG0

lvcreate -n vm_root -L 8G   /dev/VG0

Re: [Xen-users] help launching a Centos 5.5 Xen PV guest on an OpenSuse 11.2 Dom0 host ?

Hello,

You are mixing HVM and PV type installs.
I take it for granted that you prefer PV type, so lets remove
the HVM hybrid entries.

your devices (disk=) are fine, specifying xvdi for PV.

You might be surprised to find out that the C5.5 netinstall ISO is
equivalent to using the xen aware boot files (vmlinuz, initrd) that you
D/L''d separately. So you can ditch any mention of hdc or cdrom.

The disk line with xvdc should be changed - xvdc is reserved (IIRC).

boot = ''d'' is HVM only (remove)

try it again with the changes. You will get the askmethod menu by virtue of
the boot files.

wasn''t sure what the netinstall cont''d -- so DL''d to
be sure.  good, then.

a bit confused.  how/where do I inform the install where the installer
.iso is, and how it''s available?

is the presence of

kernel= ...
ramdisk= ...
extra=''... method=http://mirrors.kernel.org/centos/5.5/os/x86_64
...''

sufficient to get to the installer?

reserved in/by/for Centos?  i''ve been using xvdc for opensuse guests
for ages.

simply skip xvds, then, and use xvdd instead?

hm.  again, have used that for PV clients for awhile.  need to read up.

Let''s try something simpler. You specify

vfb          = [ ''type=vnc, vncdisplay=106,
vnclisten=127.0.0.1'' ]

It creates a vnc display for domU''s GUI.
By "hang", do you mean the output of "xm create -c"
didn''t continue,
or are you looking at the GUI? Cause by default the graphics console
will be used as default output, so you must use VNC to access it.

You could always remove the vfb line, and have xen text console  (the
one you access with "-c") becomes the default.

If it still doesn''t work, try older kernel/initrd version (5.0, or 5.2
perhaps) for installation. I had a problem earlier installing 5.5 on
newer kernel/xen version, and when I use 5.0 kernel and initrd for
install it just works. Didn''t have the time to investigate yet, so
I''m
not really sure what went wrong then.

clear.  i''d tried accessing the VNC console, but no connection was
apparent/available

i''d thought that,

  ''textmode=1 xencons=xvc0''

switches the default to textmode ... or at least that''s the way it
workd for my opensuse guests.

anyway,  by removing the vfb line, i do (!!) get to:

Nope. You''d need "console=xvc0" to force the kernel to use
xen console
as the default output.

Start by:
- removing all network setup lines from your "extra" settings. You can
easily set it up later.
- verify that the network is correct. You used

vif          = [ ''mac=00:16:3E:01:06:00, bridge=brA,
vifname=vif.A'' ]

I wouldn''t use a dot (.) in interface name, since it''s usually
used
vor vlans. Just use something like "vifA-eth0".
Also make sure the bridge you chose is working. In Centos, it''s much
easier to start with the builtin virbr0, which is NAT network with
DHCP.

that''s where the problem lies.

using in my xen cfg,

extra        = ''textmode=0 xencons=xvc0 elevator=noop lang=en_US.UTF-8
keyboard=us timezone=America/Los_Angeles ip=192.168.1.106
netmask=255.255.255.0 gateway=192.168.1.1 dns=192.168.1.1 noipv6''

i get to VNC console, and can select device = "eth0", method
"http:", and enter host/dir distro info.  the installer then starts
downloading ... removing ''bootproto=static'' seems to do the
trick;
specifying "ip=x.b.c.d", rhater than "ip=dhcp" is
sufficient.

when i add any of

 device=eth0
 url=http://mirrors.kernel.org/centos/5.5/os/x86_64/
 method=http://mirrors.kernel.org/centos/5.5/os/x86_64

however, they''re simply ignored; the installer just ignores them,
re-asking me for those inputs @ console.

apparently, those are not the correct variables/formats.

what are the correct entries for device, method, & source url -- NOT
using a kickstart file -- on the xen config''s "extra=" line
for
Centos?

thanks.

Re: [Xen-users] help launching a Centos 5.5 Xen PV guest on an OpenSuse 11.2 Dom0 host ?

the missing piece was, apparently,

  extra = ''... ksdevice=eth0 ...''

rather than,

  extra = ''... device=eth0 ...''

even to no ks is used.

i''m up & running in the Centos installer now.

thanks for the help!
