Domain Technologie Control Forum

- I did a manual install of the first dtc-xen VPS (where DTC shall be installed.)
- Setup was from Debian repo. (No GIT version)
- one specialty, the fqdn domain is resolved like d.example.com since the testbox has only a dyndns adress from outsite the lan. I canged the FQDN to example.com below.

IP for node00001: 192.168.6.10
IPs for the Test VPSs: 192.168.6.11 - ....

Code:

node00001:/usr/sbin# dtc_setup_vps_disk 01 10240 256 Redirecting standard output to /var/lib/dtc-xen/mnt/01.stdout... Redirecting standard error to /var/lib/dtc-xen/mnt/01.stderr... node00001:/usr/sbin# dtc_reinstall_os 01 10240 256 192.168.6.11 debian Redirecting standard output to /var/lib/dtc-xen/mnt/01.stdout... Redirecting standard error to /var/lib/dtc-xen/mnt/01.stderr... node00001:/usr/sbin#

Here the outputs from the logs (I observerved the logs with tail -f during the installation)

Code:

node00001:~# tail-f /var/lib/dtc-xen/mnt/01.stdout I: Configuring tasksel... I: Base system installed successfully. Customizing vps... Making VPS devices with MAKEDEV generic Copying modules... Unmounting proc and filesystem root... Install script finished

The only one line in stderr

Code:

node00001:~# tail -f /var/lib/dtc-xen/mnt/01.stderr mke2fs 1.41.3 (12-Oct-2008)

I switched to another terminal on the workstation (not the VPS BOX)

Code:

me@mydesktop:~$ ssh xen01@node00001.d.example.com xen01@node00001.d.example.com's password: Linux node00001 2.6.26-2-xen-686 #1 SMP Thu May 28 18:35:28 UTC 2009 i686 The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

Error: Domain 'xen01' does not exist. Connection to node00001.d.example.com closed. me@mydesktop:~$

Any ideas what is going wrong?

Maybe you want to start your VM with "xm create -c xen01" ?

Hi Thomas,

thanks for this hint, but I did it. However, I not realized the output of the start script. It was late last night. Sorry for that.

The last lines point in a different direction.

Code:

[    0.285537] List of all partitions: [    0.285564] 0801   10485760 sda1 driver: vbd [    0.285583] 0802     262144 sda2 driver: vbd [    0.285599] No filesystem could mount root, tried: [    0.285622] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)

So I checked the lvm "disk"

Code:

node00001:~# lvscan   ACTIVE            '/dev/lvm1/var' [2.79 GB] inherit   ACTIVE            '/dev/lvm1/tmp' [380.00 MB] inherit   ACTIVE            '/dev/lvm1/root' [380.00 MB] inherit   ACTIVE            '/dev/lvm1/usr' [4.66 GB] inherit   ACTIVE            '/dev/lvm1/swap' [3.72 GB] inherit   ACTIVE            '/dev/lvm1/xen01' [10.00 GB] inherit   ACTIVE            '/dev/lvm1/xen01swap' [256.00 MB] inherit node00001:~#

Code:

node00001:~# vgdisplay   --- Volume group ---   VG Name               lvm1   System ID                Format                lvm2   Metadata Areas        1   Metadata Sequence No  26   VG Access             read/write   VG Status             resizable   MAX LV                0   Cur LV                7   Open LV               5   Max PV                0   Cur PV                1   Act PV                1   VG Size               148.11 GB   PE Size               4.00 MB   Total PE              37917   Alloc PE / Size       5674 / 22.16 GB   Free  PE / Size       32243 / 125.95 GB   VG UUID               7Cu91N-H4ju-1Ybk-AEPw-hmtP-g3Sw-Ykrv5G

Code:

node00001:~# cat  /etc/dtc-xen/dtc_create_vps.conf.sh #!/bin/sh # This the configuration file for dtc-xen setup scripts (called uppon VM reinstallation) NODE_NUM=00001 NODE_DOMAIN_NAME=d.example.com DEBIAN_REPOS="ftp://ftp.debianclub.com/debian" NETMASK=255.255.255.0 NETWORK=192.168.60.1 BROADCAST=192.168.60.255 GATEWAY=192.168.60.254 LVMNAME=lvm1 VPS_MOUNTPOINT=/var/lib/dtc-xen/mnt DEBIAN_RELEASE=lenny KERNELNAME=2.6.26-2-xen-686

Code:

node00001:~# cat /etc/fstab # /etc/fstab: static file system information. # # <file system> <mount point>   <type>  <options>       <dump>  <pass> proc            /proc           proc    defaults        0       0 /dev/sda1       /               ext3    errors=remount-ro 0       1 /dev/mapper/lvm1-root /root           ext3    defaults        0       2 /dev/mapper/lvm1-tmp /tmp            ext3    defaults        0       2 /dev/mapper/lvm1-usr /usr            ext3    defaults        0       2 /dev/mapper/lvm1-var /var            ext3    defaults        0       2 /dev/mapper/lvm1-swap none            swap    sw              0       0 /dev/scd0       /media/cdrom0   udf,iso9660 user,noauto     0       0 /dev/mapper/lvm1-xen01  /var/lib/dtc-xen/mnt/01 ext3    defaults,noauto 0 0 node00001:~#

So two facts are strange to me, as I read in the forum, the machines are called xenXX in /var/lib/dtc-xen/mnt/

My machine is called XX (= 01) only?

Secondly, the folder/var/lib/dtc-xen/mnt/01 is empty. (I'd have expected an /etc/fstab there.)

Code:

node00001:/var/lib/dtc-xen/mnt/01# ls -al total 8 drwxr-xr-x 2 root root 4096 2009-06-19 23:21 . drwxr-xr-x 3 root root 4096 2009-06-19 23:21 .. node00001:/var/lib/dtc-xen/mnt/01#

Do I miss something in the configuration steps?
Any comments, advices welcome.

Hi,

Everything is absolutely normal here, it's also normal that you don't see the filesystem in your dom0, as it's not to be mounted permanently. The only issue (I'm guessing) is that you need a ramdisk entry in your xen01 startup file in /etc/xen/xen01. Something like this:

ramdisk = "/boot/initrd.img-2.6.26-2-xen-686"

Try this and let me know.

I'm moving this post to the dtc-xen forum by the way.

Thomas

A short summary:

Problem:
After manual setup of the first virtual machine, the log-on to that machine via ssh failed. (Even the password was accepted)

The ssh console gaves following message back:

Code:

Welcome to dtc-xen ssh console! Error: Domain 'xen01' does not exist. Connection to node00001.d.example.com closed.

Solution:
A ramdisk entry was needed for this VM:
- Logon to your dom0
- open the configfile of your machine (in this case) /etc/xen/xen01 with an editor.
- add an ramdisk to that file e.g. like for the kernel in that case:

Code:

ramdisk = "/boot/initrd.img-2.6.26-2-xen-686"

- save teh config, and start the VM

Thanks to Thomas for his help, and the whole team for this great piece of software.

FYI: the latest version in SID, or the one in our repository, has options for the ramdisk. The Lenny version doesn't have it. You might want to upgrade dtc-xen, and configure it correctly, so it adds the option correctly.
