Falko: when i follow this howto ,before I create the image which xen-vserver should i be booting into i think its 2.6.18-6-xen-vserver-686? below is the first boot: a)networking seems strange b)when i created the image i used debian:~# xen-create-image --debootstrap --hostname debian --ip=192.168.198.100 --gateway=192.168.198.1 --dist=etch c) what will the user name and password be? ----------------------------------------------------------------------------------------------- debian:~# xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 295 1 r----- 470.4 debian 1 128 1 ------ 36.4 debian:~# xm console debian Linux version 2.6.18-4-xen-vserver-686 (Debian 2.6.18.dfsg.1-12etch2) ([email protected]) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #1 SMP Thu May 10 04:02:17 UTC 2007 BIOS-provided physical RAM map: Xen: 0000000000000000 - 0000000008800000 (usable) 0MB HIGHMEM available. 136MB LOWMEM available.

What's in /etc/network/interfaces? Did you set passwd = 1 in /etc/xen-tools/xen-tools.conf? Then you should have been asked for a root password.

Is this from the host or the guest system? I think you should use a static IP on the host. You must create a vm after you've modifed the setting. The modification has no effect on existing vms.
you wrote: >Is this from the host or the guest system? 2.6.18-6-xen-vserver-686 which i think is the host i think the guest is xen-linux-system-2.6.18-4-xen-vserver-686 debian please look at the howto this is what i followed you wrote: >I think you should use a static IP >on the host. how to set a static ip for the host? i checked the actice connection information on 2.6.18-6-xen-vserver-686 interface wired ethernet (eth0) IP address: 192.168.198.128 broadcast address: 192.168.198.255 subnet mask: 255.255.255.0 default route: 192.168.198.2 primary DNS: 192.168.198.2 sec DNS 0.0.0.0 hardware address 00.0C.29.87.E0.79 you wrote: >You must create a vm after you've modifed the setting.

The host and the vms are running the same kernel. http://www.howtoforge.com/perfect_setup_debian_etch_p3 xen-delete-image http://www.howtoforge.com/xen_tools_xen_shell_argo
static ip on host i am not sure if this will work but can i take your use your example also ? ie # This file describes the network interfaces available on your system # and how to activate them.

will it work I am about to follow the static ip howto i have two questions in this thread first i will use this in /etc/network/interfaces: auto eth0 iface eth0 inet static address 192.168.0.100 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 question 1 if i restart networking at this point it may not work as /etc/resolv has not been amended? here is /etc/resolv.conf #generated by networkmanager, do not edit search localdomain nameservers 192.168.198.2 * *(this looks like the same ip as per my post before (no7)with the netstat -nr command as the gateway) this is my /etc/hosts file: 127.0.0.1 localhost 127.0.0.1 debian. localdomains debian # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts question2 looking at the files above (/etc/resolv.conf and /etc/hosts) is it ok to place the place the same nameservers as in the howto and the same example as in the howto for /etc/hosts? hotchilli
As I said before, you must use an IP address from your subnet. If you're using 192.168.198.* in your subnet, then you must use an IP from that subnet, not 192.168.0.100. Yes. Depends on the system's IP address and the hostname you want to use.
example to use thanks for your post so i could use something like this ip address 192.168.198.100 netmask 255.255.255.0 network to be determined by system broadcast to be determined by system gateway 192.168.198.2 (netstat -nr in thread 7 gives this gateway) ihotchilli
Try this: Code: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface #allow-hotplug eth0 #iface eth0 inet dhcp auto eth0 iface eth0 inet static address 192.168.198.100 netmask 255.255.255.0 network 192.168.198.0 broadcast 192.168.198.255 gateway 192.168.0.2
static ip I tried as you suggested and: debian:/home/andy# nano /etc/network/interfaces debian:/home/andy# /etc/init.d/networking restart Reconfiguring network interfaces...SIOCDELRT: No such process SIOCADDRT: Network is unreachable Failed to bring up eth0. done. so I did a rough workaround address 192.168.198.100 netmask 255.255.255.0 gateway 192.168.198.2 but when did /etc/init.d/networking restart it restarted but back to the orginal ip so I killed dhclient, but when did /etc/init.d/networking restart again dhclient pid returned. so as a last resort i killed dhclient, dhcdbd, and network manager then /etc/init.d/networking restart that did it so now i have a static ip after reboot its still in place. have not amended the /etc/resolv.conf file, is this neccessary? have not amended the /etc/hosts file for example if i added the this line to /etc/hosts(see post no 9 at the bottom) 192.168.198.100 server1.example.com server1 then run echo server1.example.com > /etc/hostname /bin/hostname -F /etc/hostname --would this be ok? hotchili hotchilli
Not if name resolution is working ok on your box. Yes, if you want to use server1.example.com as your hostname.
Falko thanks for your suggestions in this thread. So to go back to the fist post in this thread: I wil now use a command line similar to this one: debian:~# xen-create-image --debootstrap --hostname debian --ip=192.168.198.100 --gateway=192.168.198.1 --dist=etch --passwd a) since 192.168.198.100 has been used as my static ip must i choose a diffrent ip address or must i create a 2nd static ip address? b) can the gateway of 192.168.198.1--- can this be used? or should the same gateway as used for the static ip address be used ie 192.168.198.2? c) I will set this passwd = 1 in /etc/xen-tools/xen-tools.conf and add --passwd in the command line.? d) If i set a hostname (as suggested in thread no 14) then can i give this hostname in the comand line or is a 2nd hostname required? hotchilii
You must use an unused IP address for the VM, so if you use 192.168.198.100 on the host, you must use a different IP address (e.g. 192.168.198.101). Use the same gateway that you use for the host. Then you don't need --passwd on the command line. You should assign a different hostname to your VM.
