Thanks very much Eric! This is exactly what I guessed, I just wondering where I could find this piece of code and control the the pause time of guest, while the snapshot being taken? thanks !

Hello folks, If I give command to take external disk-only live snapshot, such as # virsh snapshot-create-as vm1 snapshot_vm1 --disk-only will the guest OS be paused or suspend while the snapshot being taken? Thanks very much! Best, Yuanzhen

yes, I got your point, thanks very much Eric. If I want to take a distributed snapshot, which need pause all the VMs and then take snapshot, how can I control the pause for all the VMs? Is there only way that I turn to freeze/thaw functions? and freeze/thaw only for file systems, not for the whole guest, am I right? Thanks a lot!

I must not be understanding something trivial that I cannot find in the documentation. I am running Xen 2.0.5 with Fedora Core 3 successfully. I have a VM (VM4) running a test shell script that loops infinitely while writing the date and a counter every second (to /tmp/counter). The entire VM is using a file-backed VBD for all storage (/vm-images/vm-4-disk acting as sda1 to the VM). Running

Hi folks, I need to trace how libvirt talk with qemu monitor, log everything when give command, but does anyone know what the format, and how to read the log file? for example: 2014-07-22 17:25:22.984+0000: 18571: debug : qemuMonitorIOProcess:356 : QEMU_MONITOR_IO_PROCESS: mon=0x7f733c000a40 buf={"timestamp": {"seconds": 1406049922, "microseconds": 983916},

I am using a VM with CentOS 5.8 x86_64 under KVM. I only have console access to the VM through a virtual console (web based). Tonight, after a routine "yum update", I did a "shutdown -r now" due to kernel update and the VM won't start. See console screenshot vm1.png: https://vmail.noa.gr/files/vm1.png There is an error (which I haven't seen before): type=1404

Hi, first of all, my name is Karsten and I am fairly new to xen. A former colleague of mine has set up a xen dom0 with 4 virtual machines runnig on it.

Hello, My testing machine has 2 quad-core CPU (It supports hyperthreading, but i disable it in BIOS). I uses Xen 4.0.1 as the hypervisor. When I use 8 VMs to conduct a test, CPU affinity of the VMs is very strange. Like this: vm_name vcpu_num cpu_affinity Domain-0 8 any VM1 4 1,3,5,7 VM2 4 1,3,5,7 VM3 4 1,3,5,7 VM4 4

Hi everybody, I recently used xyplot, but I found that for control flow can't work in the xyplot. The program code and some of my data file are shown as follow. Would someone please tell me where my code is wrong and how can make the code right? Thanks. Best regards Yuanzhen Lin Code: library("lattice") plot.data$Fam<-as.numeric(plot.data$Fam) #### xyplot can work if one
