Re: [Xen-users] Installing with iso

Hi Lance,
That would be great. Please let me know if you are able to crack this guest
installation. I am trying to do a comparative study between
credit and SEDF schedulers by applying different kinds of load on the system. I
am looking forward to using the guest from rpath as it
would be a good network monitoring tool to test the efficiency of the
schedulers.
Below is the content of the config file which I used for creating the rpath
domU.
kernel = "/boot/vmlinuz-2.6.18.8-xenU"
name = 'rpathns'
vif = ['']
dhcp = "192.168.31.30"
disk = ['file://srv/xen/domU/rpath-1.0.5-x86.img,sda1,w']
root = "/dev/sda1 ro"
on_reboot = 'restart'
on_crash = 'restart'
vfb = [ 'type=vnc,vncdisplay=1,vncpasswd=test,vnclisten=0.0.0.0' ]
extra = "TERM=xterm xencons=tty console=tty1"
there is no ramdisk specified. Is this intentional ? Does your kernel
boot directly without the ramdisk ? may standard kernels may not be able to.
When I do xm create, I get the message 'started domain rpathns'. Also, xm list
shows the guest to be in blocked state. But when I try 'xm
console rpathns', it takes me into the prompt " (repair filesystem) 1 #".
I tried fsck from this prompt and I get the below message ..
(Repair filesystem) 1 # fsck
fsck 1.37 (21-Mar-2005)
e2fsck 1.37 (21-Mar-2005)
The filesystem size (according to the superblock) is 437597 blocks
The physical size of the device is 418832 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>?
But i am able to abort this and I find myself at /root inside the guest OS. But
I am not sure how to start the network management
application. Please try this config and let me know if you are able to succeed.
that may be a repair prompt. The actual system may be read-only mounted.
If the block sizes are different then there has been a resize or a corrupt
filesystem. Since the specified disk is a file you can take it offline and
check it using e2fsck (if it is ext3).
Do not try 'y' answers on fsck. The best bet is to do a
resize2fs -f -p <file> just to first try to resize the FS and then
try to do an fsck and then run the guest OS.
Also, double check your fstab. Does it show /dev/sda1 as / ?
Thank you
Regards
Ananth

Hi,
May be we could write to rpath regarding this and ask for more help. I
tried creating the same using my own config file, which does not use the
pygrub. I have specified the domU kernel from my system, and I have not
used the blktap driver. Instead I have pointed to the image using the
file:// context. When I create the guest domain, it says error reading
the filesystem and tells me to run fsck. I am unable to attach my config
file right now as . I shall do that tomorrow from my lab. You can try if
you are able to make progress using that.

Hi Lance,
I have been pretty much following the link to rpath Wiki for
installing
guest domain, especially the network monitoring system which the
wiki
page points you to. I have been facing error while I create
guest using
the procedure given. I am facing the error that says pygrub did not
return any value.Please try it and let me know if you are able to
successfully create the guest domain.
Thank you

Hi,
I am running the latest xen package on
Debian Lenny
and I want to
install a Linux vm with an ISO image.
How best do I make this happen.
I have not been able to get virt-manager to
connect
to the xen
instance on my server from my Laptop.
I would really appreciate the help
Thanks
Lance
Hello Lance,
The easiest way I have found is to loop mount
the iso
then expose it on
my webserver. I then use virt-manager to connect and
install with http.
That way I am able to install in paravirtual
mode rather
than HVM.
You can also do the exact same thing from the
command
line using ssh
from your laptop, look at the virt-install man
page. I
would tcpdump on
your laptop and server to see why you are unable
to connect.
Hope that helps,
Jon

Hi again,
Is it possible for a person to run a downloaded raw file
system in a
xen environment?
I have downloaded a vm from the rpath.org
<http://rpath.org> <http://rpath.org>
site and want to run the vm
on my xen system. It is a running file system that just
needs to be
booted.
I have manually created config files on my kvm qemu
system
to run this
in the past. does xen have config files I could copy
and use?
I apologies for the newbie questions.
Thanks
Lance
I have never used rpath images but a quick look on their
site I
found
the link below. The first link about using a domU created by
rpath or
rmake and how to install it on a xen system might give
you an idea.

Hi Jon,
I must be blind. I looked on their site and did not find
that one.
Thanks again.

Hi Ananth,
I get the same error when I run xm create. I wonder if pygrub needs
more that the documenation is telling us.

Hi Ananth,
I know a few people at rPath.
I will ask them.
