similar to: HA Xen cluster live migration

Hello gurus, I have two physical xen hosts and when I migrate a domU from one host to another, I get many of this error from domU kernel: clocksource/0: Time went backwards: delta=-3536123661 shadow=686019823475 offset=281887188 Sometimes domU time stalls and network stops working, but other times it gets working again. The two hosts are using different platform timer source:

Hi, I am trying to (live-)migrate a paravirtualized machine from hosta to hostb: -----8<---- hosta:~ # xm list pvm Name ID Mem VCPUs State Time(s) pvm 64 384 1 -b---- 0.5 hostb:~ # xm list pvm Error: Domain ''pvm'' does not exist. hosta:~ # xm migrate pvm 192.168.0.2 Error:

Hi, For various bad reasons I must run a kernel 2.2.X and I tried to get it running on Xen 3.0.3. The virtual machine freeze every 28s (or less) for 1-3 secs which makes it unusable as demonstrated by: # while true; do date; sleep 1; done Thu Oct 26 18:03:36 PDT 2006 <missing> Thu Oct 26 18:03:38 PDT 2006 or # ping my-xen 64 bytes from 172.21.1.102: icmp_seq=0 ttl=255 time=8.5 ms 64

Hi folks, I read quite some posts about "Destination host unreachable" problems before, but none could help me to solve my issue. So here we go: This is what I am using: SUSE Linux Enterprise Desktop 10 SP1 - Current with all updates Network configuration of my dom0: foobar:~ # ip a 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd

Hello, I searched the mail list, but can''t find a solution. I have a machine with 8 cores. I want to set the CPU affinity for dom0. For example, let Dom0 use processor 0-3, let guests use 4-7 For guest domains, I can do this by setting the "cpus" For dom0. there''s no such option. The only one I know is in /etc/xen- config.sxp, which has "dom0-cpus" setting.

Hi, Not totally new to Xen but still very green and meeting some problems. Feel free to kick me to the DRBD people if this is not relevent here. I''ll be providing more info upon request but for now I''ll be brief. Debian/Squeeze running 2.6.32-5-xen-amd64 (2.6.32-21) Xen hypervisor 4.0.1~rc6-1 and drbd-8.3.8. One domU configured, with disk and swap image: root =

Hi, I'm wondering about the impact of using both dom0 and domU's on a server at the same time. I'm worried about the performance impact of running a Mysql server in a domU and now I'm thinking about moving the Mysql part of a LAMP setup into dom0 and running a few Apache guests as domUs. Since the Apaches will serve mostly from an NFS share they won't have much impact on

Hi, I want to add 2 vlans by the following steps: 1. add the vlan interfaces: vconfig add eth0 100 --vlan100 vconfig add eth0 101 --vlan101 2. modify the network-bridge script by the websit, http://wiki.xensource.com/xenwiki/XenNetworking#head-04ebcc1760dbc4678e83b116afa310dc0612dc39 Comment each time ifup or ifdown commands are executed.The reason is that ifdown ends with

Hi, during some experiments with many guests I get crashing Dom0s because of too less memory. Actually the OOM killer goes ''round and kills random things, preferably qemu-dm''s ;-) The box in question has 128GB of memory, I start with dom0_mem=8192M (or 16384M, doesn''t matter). I also used "dom0_mem=8192M,min:1536M", but that didn''t make any

Hi all, I''m a total xen-newbie ... I''ve installed xen-3.0-testing from source. (http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads/xen-3.0-testing-src.tgz). I''ve followed the intruction for the installation, dom0 work fine and domU start up without problem !!! Now, I''ve tryed to migrate the domU to another dom0 machine but I receive this error on the

Hello, can anybody help me how to configure vlans? There are vlans: vlan2 vlan3 vlan30 Server has one nic - eth0. vlan2 should be dom0 eth0(peth0) for management Each vlan3 and vlan30 should be has its own bridge. How to make it?

Hi, I''m trying to set up networking on a new machine. I''m not getting any networking from the domU''s I notice that I have two bridges being created: xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:3024 errors:0 dropped:0

Hi All, We tested the xm block-attach/detach command. It repeats block-attach/detach command for DomU and pv-on-hvm on HVM Domain. (block-attach -> block-detach -> block-attach -> block-detach -> ...) The block-attach command failed when repeating 256 times. It is because the channel had not been freed in blkfront. Therefore, it remain using the event channel. This patch is

Hello, Is it possible to run a Xen server inside of a kqemu/kvm/virtualbox VM? I am new to Xen, and Linux in general. (Just installed Ubuntu 7.10 on my main laptop) The idea would be to try and learn about Xen before attempting to deploy on real HW. -- Thanks P.S. I do have an Intel VT capable CPU, if that matters. --------------------------------- Never miss a thing. Make Yahoo

Hello, I use xen for a few months now and I upgraded to opensuse 10.3 with xen 3.1 (64bit versions) recently. Everything works fine, but there is a problem when I change xend-config.sxp to use my own network script (it''s slightly modified version of network-virtual scripts from http://en.opensuse.org/Xen3_yet_another_Virtual_Network_Concept ) instead of default network-bridge script.

HI: I need ideas on how to make this code shorter (maybe with a second loop?). The code as it is works, but in this case I only have 14 samples, but it will become insane with more, so I need a way to make it more automatic. The problem is that the output from ts1, ts2, and so on is a vector with more than one value, so I do not know how to solve this. Thanks Prenewbie The code is the

With GPLPV under 2.6.30, GPLPV gets the following from the ring: ring slot n (first buffer): status (length) = 54 bytes offset = 0 flags = NETRXF_extra_info (possibly csum too but not relevant) ring slot n + 1 (extra info) gso.size (mss) = 1460 Because NETRXF_extra_info is not set, that''s all I get for that packet. In the IP header though, the total length is 1544 (which in itself
