Hi, it seems as if it is not possible to have more than 3 nics per domU right now. If I specify more, I get the usual [...] xen_net: Initialising virtual ethernet driver. #### netfront can''t alloc rx grant refs vif: probe of vif-3 failed with error -12 [...] message - see bug #183. It was pointed out to me that it might be possible to adjust this manually in

Hi xen users, I''d like xen0 to be the controller and xenU(1) to be a firewall/router with 4 subnets (WAN, LAN, DMZ, TEAM) each with 1 of 4 physical nics attached to it. Using FC4 with xen-3.0.0-7 with linux kernel 2.6.12.6, default make world configurations, box is athlon cpu, 512M, 4 nics. On boot all nics are recognized, lspci shows them to be present. In xenU there are four ifcfg

Hi Jeremy. According to your suggestion, I recreated patches for Ingo's x86.git tree. And this patch series includes Eddie's modification. Please review and forward them. (or push back to respin.) Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen

Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners
