Package: xcp-xapi Version: 1.3.2-14 Severity: important I chose the Open vSwitch (ovs) networking mode when I installed XCP # cat /etc/xcp/network.conf openvswitch Whenever I boot a VM, I notice that the vif interface is created (e.g. vif1.0) on dom0, and the vif is added to the ovs bridge (I can see it in the output of ovs-vsctl show) However, there is no connectivity, I can't ping the

Hi All, Was troubleshooting some odd VM network issues and discovered that we're seeing dropped packets + retransmissions across multiple domU OS's and dom0 hardware platforms. xendev01 ~ # tshark -R "tcp.analysis.retransmission " -i vif7.0 Running as user "root" and group "root". This could be dangerous. Capturing on vif7.0 3.054257

I posted this to the Fedora-test list but I''ll try here. If I need to ditch fedora rpms and move to building directly from src before posting here, please let me know and I''ll do so (apologies in advance if this is the case).

Hi, In many places xen uses "unsigned long" instead of the l*_pgentry_t types to pass around page table entries. Here is a patch which fixes this in a number of places (mostly in shadow mode code). Thats what I''ve trapped in so far, maybe more of these patches follow. Fixing this is needed for adding PAE support to xen. In PAE paging mode the page table entries are 64 bit

Hi, we''re running 4 xen servers on our network with multiple network cards. During HighLoad we experince degeneration of inbound network traffic through our loadbalancer. I might found a reason for it, in Dom0 dmesg output looks as follows: [1157421.975910] eth0: received packet with own address as source address [1157421.975957] eth0: received packet with own address as source

Hi, I have a new xen hosting platform. I have given the bridge a static IP which I can ping/ssh to etc, when I create a new vm all works well apart from the networking. If I give DomU a static IP I can''t ping out from the box, Dom0 can''t ping the vm. I''m suspecting it just isn''t seeing the bridge but am unsure where to start looking. This is a very standard

Hello, I''ve recently changed my xen network setup and now, almost expectedly, my configuration has broken access to the Domus from the network, and now I need a little help. Previously, I had four interfaces, only one of which was configured to be used by both dom0 and domu. I have since created a bond between eth2 and eth3, expecting that eth0 would be automatically assigned for use

Hello, I write this mail to obtain help in using xen if possible. I am running a debian 4.0 (etch) distribution as a domain in a fedora core 6 which is Domain-0. The FC6 has the following kernel, which i downloaded from xensource: "Linux core2duo.localdomain 2.6.18-xen #1 SMP Fri May 18 16:11:33 BST 2007 i686 i686 i386 GNU/Linux" The version I use of xen is 3.1.0. The fact is that the

Greetings, I have a problem that is baffling me. My host machine is an older Dual Xeon machine that does not support HVM - PAE is supported. I have 2008.11 b98 installed as Dom0. I''m trying to install the same as a DomU. In the DomU, I''m starting the ssh service, logging in with X forwarding and starting the gui with: (dom1) jack$ pfexec gui-install The gui displays on my

Pardon me for a long detailed post but this looks pretty serious. The bottom line is that, when I attempt to shut down or reboot my simple xen-2.0.7 server running FC3 with two domUs, shutting down xendomains appears to send python into an infinite loop. This may be due to a serious misconfiguration on my part but it is certainly a big problem. If we shutdown the domUs manually first, the

Hello! I have two problems. One is, that I cannot ping a DomU from Dom0 (or any other host in my local network) and the second one is, that I cannot ping the same site (eg. www.suse.com) from two DomU''s at the same time. I have a fresh installation of openSuse 11.0 with Kernel 2.6.25.20-0.1-xen and my box has two physical ethernet cards. As far as I have investigated, eth0 is the one

Hi, we are trying to secure our Xen boxes with IPtables on Dom0 but we always seem to get cut off and can only cure it be rebooting the box. Has anyone got a sucessful config they can share that secures the server with one nic? We are using Xen 3.0.4 thanks Ian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

Thanks Jim, Looking at the logs for the working and non-working setups, the command line for QEMU is identical and the qmp commands almost the same: they both do "query-chardev" and "query-vnc" and the working setup does an additional "qmp_capabilities" which is likely not relevant. So I guess it must be in QEMU - I'll head over to the bug tracker. Thanks

Hi, I'm running samba-3.0.22, linux-kernel-2.6.16 and I'm having troubles with trusted domains. How can I find the suitable DC for each domain? Could be a resolution issue? Bellow my smb.conf and some tests. [global] workgroup = DOM1 netbios name = localhost server string = LOCALHOST Server security = ads realm = MYDOMAINCONTROLLERREALM

I am using ttylinux-xen file system image a a loopback device for the domain. I am mostly using the default configuration. I am not able to get networking on the domU. Are kernel "vmlinuz-2.6-xenU" as well as "2.6.11.12-xen0" both compiled w/o loadable module support? I guess it fails when it tries to initialize the iptables on the domU when it tries to do "modprobe".

Hi All, I am facing an issue regarding communicating a value from outside to a Guest OS (linux, solaris and windows) launched on Xen Server. I did went through this thread, but It was not completely clear. http://lists.xensource.com/archives/html/xen-users/2006-07/msg00473.html My question is - Is there a way in Xen, through which I can communicate a value from outside to a Guest OS (linux,
