Hello, I have some dom0 which have 8GB RAM, but when I look with xm list, it just shows me 6GB, I need to setup some new VM, each with 1GB, so I should have with 3VM still 5GB free, but im only seeing 3GB. Can I just create 2 new VM with each 1GB and still have 3GB for the dom0? #xm top xentop - 11:31:17 Xen 3.1.0-53.1.14.el5 4 domains: 1 running, 3 blocked, 0 paused, 0 crashed, 0 dying, 0

Hi guys, First of all, sorry for my poor english. This is my first message at this list. I''m using Xen on several machines since last November. Right now I''m having a specific problems with 2 servers: both are losing the network on dom0 but all guest systems are still running fine. Looking at those dom0 logs I''ve discovered that sometimes linux kernel OOM-Killer

Hi, I have encountered an apparently benign error on two systems where the dom0 kernel log is flooded with messages like: [52482.163855] System RAM resource [mem 0x1b8000000-0x1bfffffff] cannot be added [52482.163860] xen_balloon: reserve_additional_memory: add_memory() failed: -17 The first line is from drivers/xen/xen-balloon.c, the second from mm/memory_hotplug.c The trigger for the

We have some test servers running SLES11SP1 and we''ve updated to the latest kernel from Novell: 2.6.32.13-0.5-xen Since running the updates on these servers our xen ballooning parameters are not working. Because of memory problems in the past we set dom0 to 2048 meg of ram in grub and set the following parameters in /etc/xen/xend-config.sxp: (dom0-min-mem 2048) (enable-dom0-ballooning

Dear All, I''m new to XEN and I''m trying to get it work under gentoo 2006.0 with a patched 2.16.18-xen kernel. My system does not recognize my 2G of RAM. It only sees 512M! Adding mem=2G or mem=2000M to grub.conf did not help at all. The system continues to see only the dom0_mem=512M Can you explain me why? My grub.conf entry looks like this: title=Xen root (hd0,0) kernel

May be someone could point me to optimal xm configuration file setting for Dell Power Edge 2950,2G RAM,One Quad CPU 2.0Ghz I need to run SBS 2003 Windows Server as a guest.

I run my production DomU''s using Xen 3.4.1 at the moment with the old 2.6.18.x dom0 kernel. I just built a new Xen version (4.0.1-rc5) with jemerys git repo of 2.6.32.16 dom0 pvops kernel. When starting domains the go instantly into a paused state and eventually i see this error on the command line. [root@host test1]# xm create -c vps.config Using config file

I have a sles10sp3 vm that I''m trying to passthrough a scsi card, which has a DLT tape drive attached. Anyone doing anything similar? When I passthrough the scsi card (forced to do both ports), the vm dies when it loads, I think during udev. I''m viewing the vm through virt-manager, so I can''t scroll up and see what everything says. Is there a way to get the text xm

On a selection of boxes, ntpd running in Xen Dom0 reproducibly exhibits extermely high noise/jitter. Switching back to -default, non-xen kernel ntpd runs with very low jitter/noise. Question -- how can I ''tame'' ntpd noise & jitter when running in Dom0? Is the problem a config issue, or a bug? Already reported this downstream; everybody''s "stumped".

Hey all, just compiled xen 3.4.2 and linux 2.6.31.12.

You need to add dom0_mem=XXXm to xen or scale back the memory of domain0 with using "xm mem-set <DomId> <Mem>" command. Your domain0 used up almost all physical mem. >total_memory : 1023 >free_memory : 62 Thanks Yunfeng >-----Original Message----- >From: xen-devel-bounces@lists.xensource.com

Hi, This is slightly OT as xen is not officially supported in EL6. But maybe someone else is running it on centos6 as well and could help me out here: I have problems allocating a static amount of memory for my xen dom0. It seems to reduce when new domUs are created, even though I *think* ballooning is disabled. Can someone advise me what I'm doing wrong? I have xen-4.1.1-3 installed from
