Re: AW: [Xen-users] DomU freezes during boot

Hi Boris,

I apologise for ignoring your previous comments!

I attempted your instructions and ran virt-install like this:

virt-install -n test5  -r 1024 -p -f /vm/images/CentOS5-2.img -l nfs:localhost:/test1 --nographics

I received no errors or anything until the CentOS installer was running (right after I configured my IP address etc), I got this error:

+-----------+ Error +------------+
                       |                                |
                       | That directory could not be    |
                       | mounted from the server.       |

                       |                                |
                       |                                |
                       +--------------------------------+

I hit OK and it just confirms my details (I tried /mnt/tmp, same problem, and I also tried localhost, same problem):

Andrew,

  As i have noticed two times your mistake when creating PV DomU via virt-install is well known:-

************************************************************************************
--location <-l>  should point to NFS shared directory with loop mounted ISO image of
CentOS 5. 2 , NOT to path to ISO image itself.
************************************************************************************

That is what Red Hat Inc. and Sun Inc. taught customers to do for several years already.

I've also twice wrote to you how to do that. You can also view it third time:-

Insert your CentOS 5 DVD in the drive. Run "df -h" to find out what mount point is.  Suppose, it is /dev/hde

# dd if=/dev/hde of=/etc/xen/disks/CentOS5.iso
# dd if=/dev/zero of=/etc/xen/images/CentOS5.img  bs=1024k count=12000
# mkdir  -p /mnt/tmp
# mount -o loop,ro   /etc/xen/disks/CentOS5.iso    /mnt/tmp

Edit /etc/exports and add the line:-
/mnt/tmp
Restart Service "nfsd"

In other words make /mnt/tmp NFS shared directory at your local machine.
Run :-
# ifconfig
to find out your IP address (IP-Dom0) and run

# virt-install -n CentOS5PV -r 1024  -p  -f /etc/xen/images/CentOS5.img \
      -l   nfs:IP-Dom0:/mnt/tmp

However with Xen Hypervisor 3.3 you might have reissue
# vncviewer localhost:0
several times during installation procedure, to get reconnected
Be sure it's there on display 0 ( port 5900 ) .

Virt-install option <--nographics>  will allow you to get text mode install.

When graphical install gets done:-
# xm start CentOS5PV
# vncviewer localhost:0

When text mode install gets done :-
# xm start -c CentOS5PV

Personally, i have never suggested  you to run rinse & xen-tools on system
with virt-install ready to go.
The other person did. Keep track of your threads

Regards.
B.

Hmm, someone told me the other day that I should be using xen-tools and rinse, and NOT virt-install (see http://lists.xensource.com/archives/html/xen-users/2009-03/msg00742.html).

So which one should I use and why? And if I should be using virt-install, can someone please take a look at my initial problem that I still haven't fixed in the above thread? :p

Cheers,

Andrew

Sure,  getting this rinse bug fixed you'll get login to DomU.
I just cannot understand why old fashioned style of PV DomUs
setup ( with all kind of debootstrap's fun) seems so attractive on the system having virt-install ready to go.
Please, advise. Where i am wrong ?

Boris.

Yup. Put it before the line "1:2345:respawn:" ...
I think what happens is your domU boots succesfully, but it does not
display any login prompt on console (which is xvc0).

Oh and you should also add "xvc0" to /etc/securetty.

Fajar.
