Hi Peter, Should I assume that the virsh domfsfreeze, does not require the qemu-agent service in the guest? PS. I couldn't find the result.

Hi , Working on the simple POC : Advanced snapshot using libvirt and qemu . Following are the exact steps which are followed . 1.

Hello, what is really the difference between virsh migrate --copy-storage-all and virsh migrate --copy-storage-inc ? There are some documents talking about NBD snapshots, but the user visible semantics are incomplete. Where does the incremental stuff happen? Does it require qcow2 files? Does it work with raw files? Does "--copy-storage-inc" require existing snapshots? Does

Hi, Is it possible to freeze windows guests for a consistent storage level snapshot. I am using openstack icehouse on centos 6.6 Hypervisor: KVM Libvirt: 0.10.2 Qemu: 0.10.2 Guest OS: Windows 7 and Windows Server 2008 I was able to freeze Centos guests by issuing the command: virsh qemu-agent-command <guest_ID> '{"execute":"guest-fsfreeze-freeze"}' For CentOS

Hi, I'm trying to create an external snapshot for backup purposes. Only I get an error after the command: virsh snapshot-create-as --domain PCVIRT1 PCVIRT1-SN1 --diskspec vda,file=/var/lib/libvirt/images/VIRT1-SN1.qcow2 --disk-only --atomic --quiesce fout: internal error: kan AppArmor profiel 'libvirt-2c9c04d7-f86d-df12-da9f-9847ac8b994f' niet vernieuwen (Sorry about the

Hi!   I want to print the output all together with a single column name   s21<-c(1:1000); var21<-lapply(s21,function(x){    ns<-rnorm(78,8,9);    n<-length(ns);    Mn<-mean(ns)    Sn2<-var(ns)    return(cbind(x,Mn,Sn2)); }); var21 but my code is giving me somewhat like the following [[1]] x   Mn          Sn2   [1,] 1 7.86 10.56540 [[2]] x   Mn          Sn2  

Hi Looking in to implementing (CBT like) delta backup for KVM. The following looks promising..(last paragraph) http://wiki.qemu.org/Features/Snapshots2 * In the last para, there is a mention of copy the blocks from the disk using dirty-bitmap as reference. How to accomplish this ? block-mirror with bitmap or is there a qemu-img command ? some details would be

Hi, I'm using R to do a series of calculation and I have gotten several warnings that say "NaNS produced". Whatever I could read on line gives me an idea that this warning is produced when the number is use is a negative log or otherwise mathematically problematic. I'm getting this error while using factorial() and gamma () on strictly positive numbers (always greater than zero).

Hi, I use external snapshots to backup my guests. I use the 'quiesce' option to flush and frees the guest file system with the qemu guest agent. With the exeption of one guest, this procedure works fine. On the 'unwilling' guest, I get this error message: "ERROR 2016-05-25 00:51:19 | T25-bakVMSCmsrvVH2 | fout: internal error: unable to execute QEMU agent command

Hi all, I guess my question is stupid and has been asked a thousand times but i was wondering if it's possible to do the following things: - Cloning of a running virtual machine (hot copy) - Migrate a physical server to a virtual one.

This patch series makes suspend support in qemu alot more useful. Right now the guest can put itself into s3, but qemu will wakeup the guest instantly. With this patch series applied the guest will stay suspended instead and there are a few events which can kick the guest out of suspend state: A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the
