Hi, I have compiled xen-unstable (using hg clone http://xenbits.xensource.com/xen-unstable.hg). I have successfully booted into the dom0 kernel. output of xm list: Name ID Mem VCPUs State Time(s) Domain-0 0 932 1 r----- 591.2 But whenever I xm create, I get: # xm create /etc/xen/domu1 Using config file

I have a dom0 (Linux) with one domU (also Linux). I haven''t tried suspend and restore before, but it seems easy enough. But when I try it I get the error: % sudo xm suspend evil Error: Domain is not managed by Xend lifecycle support. ...Really? I can use other xm commands to query the domU, including xm console. The domU had to get there somehow, and since xm is the only way I

Recent xen uses xenbus to suspend PV-on-HVM guest domain. The related code in the xen-unstable tree will fall into infinite loop when guest domain failed on suspending one or more devices. The patch attached changes the logic, and raises an XendError after 1 minute waiting. The patch also makes use of "control/shutdown" entry in xenstore, allows guest kernel report the failure of the

Hi, Is there any tool out there that can help me analyze a coredump? Thanks, David. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, all, When working on adding PM support to xen, we realized that some enhancements are required to suspend/resume domU. Following is some background and thoughts, and welcome on comments. :-) Currently we use a simple approach (pause/unpause) for domU when ready to pull whole platform into a power save state, saying a S3. Because pause/unpause is out of domU''s knowledge, domU

Hello List If i have a PCI=[08:00.0](example) in any DomU config file the xm shutdown <ID> shuts down this DomU and the Dom0! Otherwise i shutdown this DomU from inside the DomU with halt or shutdown -r now, the Dom0 shuts down to. This happend on Xen 3.4.2 and Xen 4.0 (Kernel 2.6.18.8-xen, 2.6.18.8-xen0) The Operating System to Compile xen was Debian Lenny and the Dom0 os. Without

I am not sure if it''s a xen bug or lvm bug, or just my bad hardware, but here''s how to reproduce: /dev/vg0/centos1 is lvm block used by a domainU, it''s 8G in size. #lvcreate -L8192M -s -n snap1 vg0 #mount /dev/vg0/snap1 /mnt do some copying files here #umount /mnt #lvremove /dev/vg0/snap1 not removed! it says can''t allocated memory #xm mem-set 0 512 #lvremove

Hi, I tried to issue: xm save VMID FILE, and got the following error: Error: Error: [Failure instance: Traceback: twisted.internet.error.ConnectionRefusedError, Connection was refused by other side: 111: Connection refused. xm create works fine, xend is running on domain 0, I can log in the VM through xm console VMID and ssh without problems. I can also stop and restart the domain.

Hi, I''m building Xen on a 64bit machine, then using the xen.gz from that on a 32bit host (so that it can boot 64bit guests). This works fine. However I note that after booting xen.gz from 3.2-testing /proc/cpuinfo has different flags. 3.2.1 is the same. I have not yet tried 3.3.x. 3.2.0 results in: flags : fpu de tsc msr pae mce cx8 apic sep mtrr mca cmov pat pse36 clflush

We have tested the latest xen on VT platform with Intel 915/E8500 chipset. Here is the test summary: Issues: - Cannot boot Windows 2000 - Only one CPU is detected in SMP dom0 - Destroying VMX with 4G memory may make xend hang on IA-32e IA-32: + Build&Boot UP xen0 without problem + Can bootup unmodified IA-32 2.4/2.6 linux in VMX domain + Can bootup unmodified IA-32 WindowsXP SP1/SP2

I ran some iperf tests today and it looks like the etherbridge is the limiting factor on throughput. In the beforetime, I saw great throughput to the VMs; over 800 Mbps. With the bridge, the numbers are in the 400s somewhere. Is this the speed I can expect from the bridge? Is there some tuning I should try, or another way to get more bandwidth into the VMs? This is with xen-2.0, 2.4.27-xen0

Hi, can someone explain the states shown by the ''xm list'' command? ''r'' (running) - The domain is currently running. - This flag is always shown for the Domain 0, but never for unprivileged domains, why?

While VNC is good enough, it doesn’t work if the NIC is down. So is there a way to switch amongst guest VM’s once a crash cart’s monitor/keyboard/mouse is attached to the video/USB/etc. ports (on the back of the physical box running XEN)? For the network down (out-of-band) emergencies, is there a way to switch amongst domain and/or guest VM consoles once a crash cart ‘terminal’

Just wondering if this is a known bug? Trying to migrate the VM off to a diff dom0 results in the below error. Other VMs migrated off fine (started at around the same time as this vm) and I''ve tried a few different target servers, all resulting in the same thing.
