Package: xen-utils-3.0.3-1 Version: 3.0.3-0-4 Severity: critical File: xen Justification: breaks the whole system
We have a major issue at present which i'm finding difficult to resolve. I have 3 x physical hosts all running Debian Etch and Xen 3.0.3-1 hypervisor on each running 4 x Debian Etch Virtual Machines. The hypervisor is configured with network-nat and vif-nat. These hosts have been inherited by me to look after from a previous colleague. They have been working fine with no traffic issues for the last 2 years up until the last week whereby I noticed virtual machines just randomly dropping their connection to the host and vif generated interface. It drops the connection for approx 30-40 seconds (sometimes longer) and the all of a sudden decides to kick in and work again. I can still connect to the virtual machine via xm console machinename.domainname.com and logon whilst it looses it's network connection. On the virtual machine i run a ifconfig and it shows the correct IP / Mac, however when i run route -n it struggles and hangs to get the gateway address (ie; the VIF for the host). I can ping the virtual machines static IP address, but can not ping the default gateway (ie; the VIF). When i run a tcpdump on both the virtual machine eth0 and the physical host vif interface i can see a load of arp requests on both. ie; who-is at xx.xx.xx.xx tell xx.xx.xx.xx. After 30-40 seconds it decides to clear itself and continue the traffic. It must have been a long standing issue over the 2yrs however as we are generating more and more traffic to the virtual machines i think it's becoming overloaded and stopping the VM from accepting any incoming/outgoing connections until it clears itself somehow. Problem is i don't know how to troubleshoot this within Xen. I tried using the xen-bugtool however i get a python error stating "ImportError: No module named xen.util". What steps do i need to carry out to troubleshoot and resolve my issue? -- System Information: Debian Release: lenny/sid APT prefers oldstable APT policy: (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.18-6-xen-vserver-amd64 (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages xen-utils-3.0.3-1 depends on: ii iproute 20061002-3 Professional tools to control the ii libc6 2.7-6 GNU C Library: Shared libraries ii libncurses5 5.6+20080203-1 Shared libraries for terminal hand ii python 2.4.4-2 An interactive high-level object-o ii python-central 0.5.15-0.1 register and build utility for Pyt ii udev 0.114-2 /dev/ and hotplug management daemo ii xen-utils-common 3.1.0-1 XEN administrative tools - common ii zlib1g 1:1.2.3.3.dfsg-11 compression library - runtime Versions of packages xen-utils-3.0.3-1 recommends: ii bridge-utils 1.4-1 Utilities for configuring the Linu ii xen-hypervisor-3.0.3-1-amd64 3.0.3-0-4 The Xen Hypervisor on AMD64 -- no debconf information _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ This email and any attachments to it may contain privileged and/or confidential information.
