xm top shows high CPU load on domU when passed PCI NICs after hypervisor update
I am running a 64 bit dom0 with a stock Debian Squeeze xen hypervisor and kernel. On top of this I am running a PV 32 bit domU that is passed two PCI network cards. This set-up had been working well for over a year, however there was a recent hypervisor update so I rebooted the dom0. Unfortunately now the domU that is being passed the two NICs is no longer able to create a PPPoe connection to

Bug#679533: Traffic forwarding issue between Xen domU/dom0 and ovs
Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-5.2 Hi, We're seeing weird behaviour regarding network traffic between a Xen dom0 and domU. I reported this issue yesterday to the openvswitch-discuss mailing list, but it seems this could also be a (regression?) bug in the xen hypervisor or the linux kernel... (we've upgraded xen-hypervisor-4.0-amd64 4.0.1-4 -> 4.0.1-5.2 and

Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-1 Severity: normal Because my networking was getting rather complex I cloned my firewall/net server as domU/dom0 to offload some services to the domU. I use bridged networking with the domU virtual adaptor connected to the internal ethernet interface used to provide services (which is normally the single port of the bridge). When I attempt to

Bug#658263: xen-hypervisor-4.0-amd64: Different network traffic values from dom0 vs domU
Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-4 Severity: normal Xen Networking[1] works by creating a new pair of virtual ethernet interfaces (vifN.M in dom0 and ethM in domU with id N) and connecting then by an internal "crossover ethernet cable". My understanding of the "internal crossover" thing is that networking statistics should be the same no matter if you measure

Question about the memory layout of xen hypervisor, dom0 and domU
Hi, I have a question about the memory layout of the Xen hypervisor, dom0 and domU. *The goal I want to achieve is: I want to show which RAM area is used by hypervisor, which RAM area is used by dom0, which RAM area is used by each domU (PV guest domain). I hope to know the above information when xen is booted as well as when xen is running some domUs. I already know that we can dedicate a fix

Bug#679533: Traffic forwarding issue between Xen domU/dom0
retitle Traffic forwarding issue between Xen domU/dom0 thanks This week again this bug occurred again so we are trying to create some kind of reproduce algorithm. First we've created two virtual machines named koekiemonster.bofh.hq.mendix.net and netappsim.bofh.hq.mendix.net. We've added 29 vifs to koekiemonster.bofh.hq.mendix.net. During this tests we've always had a ping

Bug#698651: xen-hypervisor-4.1-amd64: PMU (performance monitoring) unit may be unexpectedly enabled on Dom0
Package: xen-hypervisor-4.1-amd64 Version: 4.1.3-7 Severity: important Tags: patch Dear Maintainer, The PMU may be enabled on the Dom0 although the needed MSRs are not accessible, causing at least major noise on the xen messages ring buffer. I suspect there might also be a performance decrease, because the MSR write is trapped by Xen. Once the PC is in that state, a reboot won't help. This
