RE: [Fedora-xen] yum update breaks xen
by Todd Foster 11 May '06

There is a bug n the xen package that gets downloaded with yum. Just revert back to the xen package in the rpm dir in the fc5 distro and it will work. The key to finding out if it's fixed is to see if xen_install.py is present on the system.

xend terminates with RuntimeError 'Connection refused'

Hi all, I've got this problem with xend and due to my ignorance about python I can't get no further. Are any needed python libraries missing from my system? It's an FC-5 minimal installation, on which I added several python libs. Or is it a bug?

problems with xend-http-server
by Matthias Bayer 10 May '06

10 May '06

Hi, i am using official xen-3.0.1-4 on FC5 with kernel 2.6.16-1.2107_FC5xen0 x86_64. i am facing some problems with xend-http-server. i have configure the following within xend-config.sxp: (xend-http-server yes) (xend-port 8000) (xend-address '') after restarting xend i am facing two different scenarios and behaviours that i don't understand/ need confirmed to see if this is a bug: scenario 1: 1) connect from remote system to http://<my_xen_system>:8000/xend/ ==> everything works fine, the xend page starts up and works 2) now connect to the same address from the xen system (from Dom0) either with a browser or by using 'wget http://<my_xen_system>:8000/xend/' ==> fails with message Connecting to <my_xen_system>|16.57.34.76|:8000... connected. HTTP request sent, awaiting response... scenario 2: first restart xend using 'service xend restart' 1) connect from Dom0 using a web browser ==> works fine 2) connect from Dom0 using 'wget http://<my_xen_system>:8000/xend/' ==> works fine as well 3) connecting from Dom0 using wget http://localhost:8000/xend/' ==> works fine 4) connect from remote system with a web browser to http://<my_xen_system>:8000/xend/ ==> works fine 5) connect again from Dom0 using 'wget http://<my_xen_system>:8000/xend/ ==> fails again ...... Connecting to <my_xen_system>|16.57.34.76|:8000... connected. BTW: if you use firefox locally on Dom0 to connect to the xend-http-server after the connection from remote was made before the system runs on a high load without doing anything .... so i guess always after connection from remote to the xend-http-server i cannot connect to it from Dom0 afterwards - at least for some time ..... also over time since i enabled xend-http-server i see some messages on my serial console saying: peth0: received packet with own address as source address did somebody also see this message? what does it mean? where does it come from ? can somebody confirm/explain the above described behaviour ? is this a bug ? regards, Matthias _______________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.

FC5, Xen & LVM
by Ignacio Verona 08 May '06

08 May '06

Hi, I'm only trying to see if I got the idea. Right now, I've a physical machine, with FC5 and one FC5 guest running. I'm using a file as VBD for the guest, and want to know exactly how the LVM stuff works on Xen. I've a spare 40Gb partition, so imagine I create a LVM volume on that partition and then I split the space into 3 logical volumes. As I need to install 3 VMs on the machine, will I be able to easily resize the partitions, so for example if suddenly I need 10Gb on one of the VMs I can "stole" that Gbs of other VM? Thanks for any reply, as I'm a little confused!

RE: [Fedora-xen] Unmodified 2003/2000/FC5 on XEN 3.0.2
by You, Yongkang 08 May '06

Hi Rafiq, Sorry for response later. The configuration should be right for FC5. I notice you build out Xen source yourself. You can try with this configuration: root (hd0,0) kernel /boot/xen.gz dom0_mem=262144 com1=115200,8n1 module /boot/vmlinuz-2.6-xen0 ro root=/dev/sda1 console=ttyS0 console=tty0 module /boot/initrd-2.6.16-xen0.img I can use above grub config to boot xen with serial output. I suggest you can use Windows XP as the Windows guest testing. :-) BTW, you Xen is pae enabled. But now the feature of “pae VMX on pae Host” is not supported. So you have to do some configuration in Windows to avoid VMX run into pae mode. :-) (Windows XP SP1 should not be pae enabled default.)

Installing a different distribution as guest
by Lars Erik Dangvard Jensen 05 May '06

05 May '06

Hi list How do I install a different distribution as a guest/domU on Fedora core 5 dom0? I just want to install ubuntu or debian sarge onto a lvm partition. Is there anyone out there with at working approach? I've tried a debootstrap for Fedora etc. but I get errors that chroot doesn't work. I've also tried to make a boot partition, but then I get kernel panic. I use the 64 bit FC5 edition, maybe that's my trouble? Thanks Lars
