domU crash

domU crash

[Patrick O'Rourke]

Apologies if this is a known issue (I scanned the archive / bugzilla and 
did not see it).

Anyway, I upated from the today's src tarball and did a make world / 
install.  Upon booting a domU I got the following crash:

> Bringing up loopback interface:  network-functions: line 137: cd: /var/run/netreport: No such file or directory
> [  OK  ]
> Bringing up interface eth0:  
> Determining IP information for eth0...Unable to handle kernel paging request at virtual address cc3de022
>  printing eip:

> Oops: 0000 [#1]
> PREEMPT SMP 

I compared the domU .config with my previous working version from 8/11 
and noticed that CONFIG_XEN_NETDEV_GRANT_{TX,RX} options are now turned 
on (the only domU config changes).  So I rebuilt the domU and it booted 
fine, network came up, etc.

I also noticed that running an install from with the domU directory 
places the domU kernel in /boot/boot:

Just to follow up, the reason is for the crash was that I had built my 
dom0 kernel with an older config (one I've been using for this machine) 
and as a result the dom0 kernel was still being built with these options 
off.  Once I enabled the options in both dom0 and domU, the issue went away.

xend is trying to look up the device number for /dev/hda1. Since your 
system doesn;t have a /dev/hda1, and you are presumably using udev, 
this lookup fails. If you created that node manually in /dev/ then all 
should be fine.

Really the device name should be passed to domU as a string, and 
resolved to a number there. Or xend can just have a table of simple 
name lookups for thing like hda, hdb, ...

I am really confused on this one, as I can get it to work no matter what
I use sometimes, other times I have seen it where it won't work unless I
only use /dev/sdXX where XX does not exist at all on the dom0.

With changeset 7353 on my UP machine I got 100% success rate of domU
creation like this, all the domU's in this case are Centos 4.1, which
uses udev. The dom0 has a /dev/sda and /dev/sdb, if I used /dev/sdaX or
sdbX on this machine I always got domU creation failures, I switched all
the domU's to use /dev/sddX and 100% creation every time.



My SMP dom0 has sda, sdb and sdc, I use lvm's for domU's all located on
sdb.

disk = [ 'phy:VG01/idom1,sda1,w' ,'phy:VG01/domain1-swap,sda2,w']
root = "/dev/sda1"


What should I be using? 

The domU's will all come up like this,with roughly 30% failure rate on
domU creation and 20% failure rate on vif creation( still digging on
this so not a big deal) and reattempting create will resolve both
issues.


It would probably save everyone some grief if this would be clarified.
Based upon what you are saying the domU should be using a device
designation that really exists, yet I regularly see where that indeed is
not the case, and sometimes has even hindered successful domU creation.

If someone would be so kind as to explain exactly how this really should
be setup it would probably increase everyones productivity involved. I
would gladly create the doc if I knew for sure what is the proper setup.

Ted

The log you sent shows the domain being successfully created and unpaused;
it should then start to boot.  What happens next?

You have a domain here, and it's already used 252 seconds of CPU time, so it's
doing _something_.  Is that time going up rapidly?  Try xm list a few times to
find out.  What's on the domain's console (xm console inhouse)?  And it's
Ctrl-] to exit the console again.

Oops. I've rebooted the hole system and now it works. :-)

Make sure you start the domU in console and have a serial console
connected to xend. You will likely have a better chance of seeing what
is happening.

How must i do that?

In normal case i do:

# cd /etc/xen
# xm create inhouse
# xm list
----> repeat until a "b" is in the state.
# xm console inhouse
----> the login prompt will be displayed.

In Xen 2.0 i've got displayed all boot messages with xm console, but now i see nothing like that. How can i view this boot informations?

Re: domU crash

Very strange things occure, when starting my domU called "inhouse". It has a lot problems with mounting my drives. Here is the configuration file:

#  -*- mode: python; -*-
 
# configuration name:
name    = "inhouse"
 
# usable ram:
memory  = 2048

# usable cpus:
cpu     = 0
maxcpus = 1
 
# kernel und initrd:
kernel  = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"
 
# boot device:
root    = "/dev/hda1"
 
# boot to run level:
extra   = "3"
 
# network interface:
vif  = [ 'mac=aa:cc:00:00:00:01, bridge=xenbr0' ]
hostname = name
 
# storage devices:
disk = [ 'phy:xenvg/inhouse-root,hda1,w',
         'phy:xenvg/inhouse-cdb,hda2,w',
         'phy:xenvg/inhouse-comserver,hda3,w',
         'phy:xenvg/inhouse-docarchive,hda4,w',
         'phy:xenvg/inhouse-home,hda5,w',
         'phy:xenvg/inhouse-journal,hda6,w',
         'phy:xenvg/inhouse-mailserver,hda7,w',
         'phy:xenvg/inhouse-pos,hda8,w',
         'phy:xenvg/inhouse-pub,hda9,w',
         'phy:xenvg/inhouse-srv,hda10,w',
         'phy:xenvg/inhouse-tmp,hda11,w',
         'phy:xenvg/inhouse-transfer,hda12,w',
         'phy:xenvg/inhouse-usr,hda13,w',
         'phy:xenvg/inhouse-var,hda14,w',
         'phy:xenvg/inhouse-swap,hdb1,w',
         'phy:xenvg/susedvd,hdc1,r' ]

And here you see, what the mount displays after successful boot of this domU, which is rarely:

# mount
/dev/sda8 on / type reiserfs (rw,acl,user_xattr)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/mapper/xenvg-inhouse--root on / type reiserfs (rw)

Well, /dev/sda8 is another bootable disk. Horrible but true: it mounts realy strange things. The /etc/fstab file looks like that:

/dev/hda1   /                 reiserfs  defaults  1 1
/dev/hda2   /cdb              reiserfs  defaults  1 2
/dev/hda3   /data/comserver   reiserfs  defaults  1 2
/dev/hda4   /data/docarchive  reiserfs  defaults  1 2
/dev/hda5   /home             reiserfs  defaults  1 2
/dev/hda6   /journal          reiserfs  defaults  1 2
/dev/hda7   /data/mailserver  reiserfs  defaults  1 2
/dev/hda8   /data/pos         reiserfs  defaults  1 2
/dev/hda9   /data/pub         reiserfs  defaults  1 2
/dev/hda10  /srv              reiserfs  defaults  1 2
/dev/hda11  /tmp              reiserfs  defaults  1 2
/dev/hda12  /data/transfer    reiserfs  defaults  1 2
/dev/hda13  /usr              reiserfs  defaults  1 2
/dev/hda14  /var              reiserfs  defaults  1 2
/dev/hda15  /data/webgate     reiserfs  defaults  1 2
/dev/hdb1   swap              swap      pri=42    0 0
/dev/hdc1   /setup/susedvd    reiserfs  ro,noauto

Do i something wrong or exists there a realy stange bug in Xen?

That's not really better:


# xm create -c inhouse
Using config file "inhouse".
Started domain inhouse

Deleting the /etc/mtab solved this.
