Moi! I upgraded Xen-2.0.1 to Xen-2.0.5 (testing) and everything compiled cleanly. I''m still able to boot dom0 and start domUs but networking doesn''t work anymore. xen-br0 appears in dom0, but vif-interfaces now only when ifconfig -a is used. Interface appears in domU and all seems to be fine, except no any data doesn''t move in any direction. I can''t even ping

I want to get couple of DomUs running with Xen. I installed Xen 4.1.5 from source on a Fedora 17 Dom0. I did some reading on configuring DomUs using xl/xm and cfg files. http://www.fclose.com/b/linux/2544/setting-up-lvm-backed-xen-domu/ http://www.fclose.com/w/Setting_Up_Xen_DomU_on_Fedora:_Unmodified_Fedora_on_Top_of_Xenified_Fedora_Xen_Dom0%23Install_Fedora_12_Linux_via_Internet So basically I

Hi, I''m currently switching from toolstacks from xm to xl. Because I have a rather complex network setup with my domUs, I use xen''s nat capabilities. But what works fine with xm behaves slightly strange in xl: I use something like the following to establish a domU interface within my vif part: ''type=vif, mac=00:16:3E:06:DA:B2, ip=192.168.2.1, vifname=fw11,

Hi, I seem to have an interesting issue with vif-route. This is after an update to Xen 4.2.1, switching from xm to xl. I have 10 PV domUs on the host and two FreeBSD ones. All the PV domUs are now working nicely. Since FreeBSD has always been just slightly broken as PV I chose a HVM domU for those, but with PV drivers. Those PV drivers all blew up now after the upgrade. I''m now trying

Hello, I have a xen server (xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p / kernel 2.6.24-28-xen). I have some domUs, one of them is a fli4l router, the others are eisfair domUs (fileserver, webserver and mailserver). All of the domUs are connected via vif network interface with a bridge in dom0. There is a problem invoking following command in every domU: openssl s_client -connect

I've set up a local webserver to store kickstart files for domUs. All parameters are respected apart from the network settings. DomU always gets DHCP. Can any one help to unwrap this one? Does one add hostname, ip, netmask and gateway values to the /etc/xen/blah.cfg file? # ---- domU kickstart file ----# url --url http://192.168.1.120/centos/5/os/i386 lang en_US.UTF-8 keyboard uk network

I am currently running a Redhat Rel5 Dom0 with a solaris 11-66 xen domU as well as a Redhat REL4 domU. I am experiancing problems similary to those described the the Aug 2006 Release notes regarding ... Solaris domUs on non-Solaris dom0s 32-bit Solaris domUs should run on any 3.0.2-3 or later dom0. The majority of our testing has been on CentOS dom0s. 64-bit solaris dom0 and domU require updates

Hello, I hope this is the mailing list to discuss this issue, but if not sorry for spamming! I just discovered a really slow IO performance on DomUs running debian wheezy over wheezy dom0s, any operation that requires disk read or write takes a lot of time. Here are the hardware parameters: Single Xeon 5120 (dual core) 8GB of ram Hardware raid 2x250GB drives raid 1 his is the configuration

Hi, I did not find any hints in the web where to configure/setup/manipulate the rx/tx ring buffer allocation within dom0 for xen-unstable, maybe someone here can nudge me towards the right knob. The problem: when booting a handful of domUs and connecting them (comprising a small experimental IP network with links and nodes etc.), some interfaces that have been given by the configuration files

Hello. My host is CentOS 5.3 and Xen is v3.2 (from RPMs provided from Gitco). One of my DomUs is Trixbox that has been having some intermittent issues that I believe are due to it being behind my firewall (which is a Linksys router). My ISP gives me two dynamic IPs, so I would like to put my Trixbox DomU on this second dynamic IP. The Trixbox DomU is an HVM DomU. What is the best way to do

Situation: Running a simple UDP client/server program where the client on one domU on one computer sends echo packets to another domU on another computer, server sends echoes back. They do this on a specified port (will use any port between 5000-6000). This program works on non-Xen machines in various environments, Linux and Solaris. Program just hangs on the domUs. I believe I need help with

Package: xen-hypervisor-3.0-unstable-1-i386 Version: 3.0-unstable+hg11561-1 Severity: important I've installed xen-linux-system-2.6.17-2-xen-k7 (version 2.6.17-9) on a server, and planned to run 3 Xen domUs on it. Creating the domUs was no problem, and running two of them works well. Starting the third one however will crash the dom0 and forces it to reboot. The machine is a Athlon64 3800+

Hi all, I have strange problem with memory allocation on my xen server. My xen server: - distro: Debian squeeze - xen-hypervisor: xen-hypervisor-4.0-i386 4.0.1-1 - boot options: /xen-4.0-i386.gz placeholder dom0_mem=256M Dom0: - kernel: 2.6.32-5-xen-686 #1 SMP - /etc/xen/xend-config.sxp: (dom0-min-mem 256) (enable-dom0-ballooning no) DomU: - name: storage - distro: Debian

hi all, I can''t create domU with the virt-manager, but I''d like to use it anyway. If I start domUs from command line (xm create ~) I can see them in the virt-manager, but they''re gone after I pause them or stop them. I assume that the virt-manager has some place where it saves config files for domUs, on linux it is usually /etc/xen/vm. I went in some obvious places

Hi all, I would like to know how to debug xen. To give some more informations, I would like to explain why I''d like to do this. I''ve compiled xen from source (3.1.x/unstable) and installed it on Debain etch. Furthermore I''ve installed 2 DomU, one HVM (Win2k3) and one EFW (Endian Firewall, RH-based 2.6.9-55 kernel). Both DomU''s are running fine for about 15

Hello list! I''ve noticed this problem a couple of times now.. so I''m wondering if it''s a known bug? Symptoms: After "long" dom0 uptime (174 days when it happened now, was something similar on previous times too) cannot start new pv domUs anymore.. pygrub runs and boots the kernel, but kernel newer gets to actually running initrd and the console output

Hello everybody The current limit (we''re working with Xen 4.0.1 on a debian squeeze server) for the domU memory is 256 Gb Is it possible to do something to get domUs with more than that ? Do we have to upgrade Xen hypervisor for that purpose or is a kernel recompilation sufficient ? We would like to have a vm with 768 Gb memory... Thanks for your kind answers ! -- Emmanuel

Dear Xen Community, today we tried to upgrade our base server from a Xeon E5430 to a Xeon X5570 (Nehalem). This worked fine so far, but our DomUs with Kernel 2.6.27 no longer boot - they start up until the following message appears: [..] Mount-cache hash table entries: 256 Initializing cgroup subsys ns Initializing cgroup subsys cpuacct Initializing cgroup subsys memory Initializing cgroup

Hi, I use a EQ 4 dedicated root server by hetzner with ubuntu jaunty. I installed xen 3.3 with debian kernel and brought up 3 domUs. Now comes networking... Hetzner does not allow bridged networking so I have to use routed mode in xen. No Problem so far, but the Problem actually is: When I bring up a domU the routing table is created by the xen-script vif-routing. The network interface name

Hello, This is my first post in this list.
