How is network bridging for Xen handled in F7?
by Christian Reiter 06 Feb '08

06 Feb '08

Hi! Can anybody tell me where i can find docs about handling network bridges for xen domUs in Fedora 7? Something changed since FC6, so i cannot figure out how to create simple bridges without dhcp for my xen domUs. All what i want is: xenbrINTERNET should bridge to eth1 xenbrLAN should bridge to eth0 eth0 and eth1 of my dom0 should also have an IP Address. I do not want routing or nat for my domUs. Thanks! regards, christian

Xen status for FC7
by Frank Morane 05 Jul '07

05 Jul '07

Hi all, I just did a fresh install of FC7 to see if xen would work out of the box. Dom0 boots (with errors in the log - see below) and some Centos 4.4 domU boots but are unseable (after recompiling the initrd image with the xen driver preloaded) up to the famous long lasting error message "4gb seg fixup". At that point it is dead My question: what id the status of Xen for Fc7? Will it ever fly? Is there a Linux distro that works out of the box ? The last usable version I saw was for FC5 as of May 2006, after that all version were badly broken and never fixed, I tested ALL of them for fc5/fc6 and not a single one worked as published. Only home brewed compiled version would work after weeks of trial and error. Here what the log says from my out of the box install: [root@paine xen]# cat xend.log [2007-06-29 08:08:34 2567] INFO (SrvDaemon:331) Xend Daemon started [2007-06-29 08:08:34 2567] INFO (SrvDaemon:335) Xend changeset: unavailable.

64bit Hypervisor on 32bit OS
by thewird 03 Jul '07

03 Jul '07

I've been reading about how to make Xen show more then 16GB of ram and still support 32bit but so far all my attempts have not worked. FC7 was supposed to be able to run 32bit guests on its 64bit OS but because of a feature freeze, this was not possible even though it still says you can do it in the release notes which I find ridiculous. Anyway, someone told me if I replace the hypervisor with the 64bit counterpart, then I should be able to see more the 16GB of memory and be able to run 32bit guests. I did this by extracting the files from the 64bit RPM and replaced the xen.gz-2.6.20-2925.11.fc7 file with the one from the 64bit RPM and rebooted. The OS booted fine, however, when I tried running/installing a 32bit domU the console would not load or would lock up almost immediately. I can't think of anything else to try and any help would be greatly appreciated. thewird

fedora7 xen questions
by Deependra Singh Shekhawat 28 Jun '07

28 Jun '07

Hi, I am using Fedora7 xen kernel version: kernel-xen-2.6.20-2925.11.fc7 and my xen version is: xen-3.1.0-2.fc7 and I am experiencing two difficulties. First is that my wireless network card is not working (intel 3945 a/b/g). I am using ipw3945 driver. It is loaded as a module when I check via lsmod. But /sbin/ipw3945d says: No Intel Pro/Wireless Device Found. It works perfectly with the non-xen kernel that is: 2.6.21-1.3228.fc7 The next thing that annoys me is that when I shut down the machine with the xen kernel it does stops all the process and at last shows my "System Halted" and it stays right there. Doesn't really shut it down. With the non-xen kernel I don't have any such problem. So are these problems are a unknown bugs ? And what steps do I need to take to eradicate these problems. Thanks Deependra Singh Shekhawat -- http://freeshells.ch/~source/

RE: FC7 SYSTEM SHUTDOWN PROBLEMS

I experienced the same problem on a Dell Latitude D620, a Dell Inspiron 8500, and 4 Dell 390s. I resolved my issues by updating by bios with the latest from dell and reloading the OS. I found and resolved this issue this way with Fedora 7 and Red Hat Enterprise Edition 5. I believe the BIOS is V 2.3.0.. Hope this helps.

CURSOR STUCK ALONG THE Y
by miguel 27 Jun '07

27 Jun '07

I'm currently attempting to running the Fedora 7 XEN kernel on a Dell 390. Specs: Intel Core 2 Duo E6600 2.40GHz/1066MHz/4MB L2/Dual-core/VT. 128MB PCIe x16 nVidia Quadro NVS 285 Graphics 2GB, 667MHz, DDR2 SDRAM Memory 80GB SATA 3.0Gb/s with NCQ and 8MB DataBurst Cache Problem: Whenever launching the virtual machine (virt-manager) the cursor gets stuck on along the Y-axis. I can freely move along the Y-axis but moving along the X-axis is almost impossible. If I slowly move the mouse it sometimes works, but normally I just get frustrated and reboot the box. Is there a configuration issue I've missed or is this a bug?

FC6 xen bugfixes planned?
by Tom Horsley 27 Jun '07

27 Jun '07

Just ran into a bug with all the HVMs I have running under Xen with a 64 bit AMD host (FC6). Apparently the int3 debugger trap instruction gets the wrong PC reported in the VMs, so it is a pain in the patoot to do debugger development on Xen guests :-). (Search google for "hvm int3 amd" and you can find references to patches that are fairly recent - a lot more recent than the version of Xen provided with FC6). Any planned bugfixes in the pipe for Xen on FC6, or should I look at swapping in some completely different host?

More then 16GB with FC6 or FC7?
by thewird 27 Jun '07

27 Jun '07

Is there any way to make the xen kernel see more then 16GB of ram when its installed on a 32bit OS (either FC6 or FC7)? I tried FC7 64bit since it can see all the ram, however the only 32bit OS I was able to install successfully was windows XP. Every other distro (FC6, FC7, and CentOS 4.5 & 5.0) would freeze up at some point in the installation or bootup section. I have a machine with 28GB of ram and have a month to get it running.
