[opensuse-virtual] Naming the virtual interface?
by Per Jessen 25 Jan '12

25 Jan '12

I've been googling a lot looking for how to use the vifname parameter to give me pre-defined interface names - there seems to be many hits discussing whether or not it is supported, but it is certainly tested in /etc/xen/scripts/vif-common.sh. I've got a vif entry with "vifname=guest112.0", but this appears to be just ignored. -- Per Jessen, Zürich (2.2°C) -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-virtual+owner(a)opensuse.org

[opensuse-virtual] After switching from "xm" to "xl" toolstack, can't get Guest networking to work.
by erin.balid＠inoutbox.com 25 Jan '12

25 Jan '12

Hi All. I inherited an OpenSUSE Version 11.4 Xen host machine here at work. Without too much trouble I finished upgrading it to Version 12.1. The old setup was running using the Xen "xm" toolstack and works like you'd expect. The new setup works ok if I use the "xm" stack as well. I learned that we should move to the "xl" toolstack. I'm trying to do that now and having some problems with networking, but only with the xl approach. I've been running up to date Xen for awhile. rpm -qa | … [View More]grep -i xen xen-tools-4.1.2_11-164.5.x86_64 xen-doc-html-4.1.2_11-164.5.x86_64 xen-libs-4.1.2_11-164.5.x86_64 xen-4.1.2_11-164.5.x86_64 patterns-openSUSE-xen_server-12.1-25.21.1.x86_64 xen-devel-4.1.2_11-164.5.x86_64 xen-doc-pdf-4.1.2_11-164.5.x86_64 kernel-xen-devel-3.1.0-1.2.1.x86_64 kernel-xen-3.1.0-1.2.1.x86_64 I already setup the networking on the Host to use OpenSUSE configuration. brctl show bridge name bridge id STP enabled interfaces br0 8000.0052351d5337 no eth0 cat /etc/sysconfig/network/ifcfg-br0 STARTMODE='auto' BOOTPROTO='static' BRIDGE='yes' BRIDGE_PORTS='eth0' BRIDGE_FORWARDDELAY='0' BRIDGE_STP='off' NAME='Motherboard' IPADDR='192.168.1.32/24' BROADCAST='' REMOTE_IPADDR='' NETWORK='' MTU='' ETHTOOL_OPTIONS='' USERCONTROL='no' NM_CONTROLLED='no' cat /etc/sysconfig/network/ifcfg-eth0 STARTMODE='manual' BOOTPROTO='none' BRIDGE='no' The Guest cfg file I'm using for testing is: cat test.cfg name='test' builder='linux' bootloader='/usr/bin/pygrub' disk=['phy:/dev/XenVols/test,xvda,w'] vif=[mac=00:16:3e:12:34:01, bridge=br0 , vifname=vifBR'] vfb=[ 'type=vnc, vncdisplay=1, vnclisten=127.0.0.1'] extra='textmode=1 xencons=xvc0 noirqdebug' on_shutdown='destroy' on_reboot='restart' on_crash='destroy' vcpus=2 maxmem=2048 memory=2048 With a clean-booted Host and no launched Guests, xl list Name ID Mem VCPUs State Time(s) Domain-0 0 1010 4 r----- 86.3 xl create -c test.cfg pyGRUB version 0.6 ┌────────────────────────────────────────────────────────────────────────┐ │ Xen4 12.1 DomU │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ └────────────────────────────────────────────────────────────────────────┘ Use the ^ and v keys to select which entry is highlighted.

[opensuse-virtual] Trying to launching any X11 applications from a Xen Guest on my local desktop doesn't open a window, and fails with an error.
by rogerhalborn＠operamail.com 11 Jan '12

Good morning, I'm consolidating a number of separate, physical servers onto a single Xen platform. I have installed OpenSUSE 12.1 as the Xen Host, and, I can install & launch OpenSUSE 12.1 Xen Guests. All of the Guests are accessible using SSH, and are generally functioning as servers as they're intended to. So far, so good. For one of the Guests, I need access to a root X11 application on it. >From what I've managed to read, I understand I can do that by "enabling X forwarding" on … [View More]
