I''m using kubuntu dapper, so /proc/sys/kernel/hotplug is disabled, and instead udevd is running to get events from kernel and do what is necessary. in my first steps with xen (unstable), I get this error: root@nandemonai:~# xm create myxm Using config file "/etc/xen/myxm". Error: Device 2049 (vbd) could not be connected. Hotplug scripts not working. root@nandemonai:~#

We have seen a series of messages when running xm-test lately on a SLES 9 SP2 32-bit box with 4GB of RAM, PAE enabled Xen build. I don''t know whether this defect of just an informational message.

Hello everyone, I''m trying to run Xenoprof (Oprofile 0.9.4) in Gentoo Linux 2.6.21-xen (64 bit) on an AMD 64 system and am facing the following two issues: 1. Xenoprof complains about a write error, but starts and runs anyway. dom0 # opcontrol --start-daemon --active-domains=0 --event=CPU_CLK_UNHALTED:75000::1:1 --vmlinux=/usr/src/linux-2.6.21-xen-dom0/vmlinux

I am having the same problem, however on RHEL 2.6.16. I have tried setting up the bridge manually but it does not work.

Hello, I''ve seen from time to time where a domU using heavy disk I/O can slow down an entire server (including all other domU''s and dom0). Is there a way to schedule or limit this in Xen 3.0.3? Thank you, Brian ** _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Changeset 8460 re-introduced sharing of I/O resources with domains other than dom0 to allow for the creation of driver domains. However, Xen currently lacks accounting of those I/O resources allowing for misconfigurations to give the same resource to multiple domains. When resources are given to driver domains, they must be manually revoked from dom0 in order to ensure that dom0 is not using that

Hi, I am using XenServer5.6 FP1 GA release with openvswitch as network backend. When I create VM through xapi, "apache.xmlrpc.XmlRpcException: I/O error" happens very frequently. At meanwhile my xencenter lost connection to hosts. Another thing is when I tried to kill VMs from xencenter, it complains "Internal error:Sys_error("Thread.create: Cannot allocate

Is it possible to monitor Core Events and Uncore Events simultaneously? Currently, it is not working now in my machine. When I type the command line like this, opcontrol --start-daemon --event=LLC_MISSES:6000::0:1 --event=LLC_REFS:6000::0:1 \ --event=MEM_UNCORE_RETIRED:6000:0x10:0:1 --event=MEM_UNCORE_RETIRED:6000:0x20:0:1 \ --xen=/boot/xen-syms-4.0.1-rc3 --no-vmlinux
