I have been using libvirt for a while now with some linux guest installed. And everything has been working great. I've got a nice new (used) HP virtual host with 12 x dual core and 48Gb mem. My Windows servers are getting old, so I found it was time to take the next step and also virtualise my Windows systems. Now I've got two Windows guests on my new host: - A Windows 8.1 which runs a

Dear Daniel, my XML's: Note: It seems I was to quick, the Windows 8.1 isn't fixed... Windows Server 2015 R2 <domain type='kvm' id='146'> <name>CmsrvAPP2</name> <uuid>02c5daef-662a-85ba-7291-485118badc64</uuid> <memory unit='KiB'>3149824</memory> <currentMemory unit='KiB'>3149824</currentMemory>

Hi, I use this procedure to backup my VM's: http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit It works on my current host: Compiled against library: libvirt 1.2.16 Using library: libvirt 1.2.16 Gebruikte API: QEMU 1.2.16 Draaiende hypervisor: QEMU 2.1.0 Now I'm doing a test on a testing host: Compiled against library: libvirt 1.2.21 Using library: libvirt 1.2.21

Hello, I did a virsh snapshot-create-as --domain meta sn1 --diskspec vda,file=/var/lib/libvirt/images/meta-sn1.qcow2 --disk-only --atomic --no-metadata Then I successfully blockcommitted 2 disks: virsh blockcommit meta vda --active --verbose --pivot virsh blockcommit meta vdb --active --verbose --pivot But when doing virsh blockcommit meta vdc --active --verbose --pivot I got: Block commit:

Hi,guys I wanna to get the disk snapshot size, but found nothing libvirt commands related,except qemu-img. I create two disk snapshots, but nothing return its' size [root@cskvm01 qcow2]# qemu-img info /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 image: /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 file format: qcow2 virtual

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

I take an internal snapshot (VM is 'shutdown' when taking it) of a qcow2 image like this: $ qemu-img snapshot -c sn1 [my_image].qcow2 I see that snapshot when asking for: $ qemu-img info [my_image].qcow but do NOT see it with: $ virsh domblklist [my_domain] is that how it is meant to be?

Hello, I would like to double check what Echo Cancellation my Digium Card uses. I thought I bought the little more expensive card that integrates EchoCancellation. How can I check? root at sn1:~# zaptel_hardware pci:0000:0b:08.0 wcte12xp+ d161:8000 Wildcard TE121 root at sn1:~# ztcfg -v Zaptel Version: SVN-branch-1.4-r4309 Echo Canceller: MG2 Is MG2 the correct one that I am supposed

hi Martin, thanks again for the feedback. maybe you have noted that I am not yet all too familiar with those tools. this is now sort of working for me. But I sense that you seem this method to be less then ideal. Reading through the virsh manual it looks like ... $ virsh snapshot-create [domain] --disk-only --live ... might be doing a similar thing. Maybe more elegant (pure virsh) and on a

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

I have a text file similar to this (separated by spaces): x <- "DF12 This is an example 1 This DF12 This is an 1232 This is DF14 This is 12334 This is an DF15 This 23 This is an example " and I know the field lengths of each variable (there is 5 variables in this data set), which are: varlength <- c(2, 2, 18, 5, 18) How can I import this kind of data into R, using the varlength

I've been trying to implement the quota system for a Linux cluster. I'm trying it out on a mini-cluster of 4 CentOS 6.3 VMs. I've named them: lion-login lion-sn1 lion-cn01 lion-cn02 All nodes are on the virtual subnet 192.168.56.0/24. lion-sn1 (storage node 1) is the NFS server and the other three nodes are the NFS clients. /etc/exports on lion-sn1: /home 192.168.56.0/24(rw)

Hi, I am trying to find a function to match two data frames of different lengths for one field only. So, for example, df1 is: Name Position location francesca A 75 cristina B 36 And df2 is: location Country 75 UK 56 Austria And I would like to match on "Location" and the output to be something like: Name Position Location Match francesca A 75 1 cristina B 36 0 I have tried with

Thanks Kashyap, The command line examples makes thing quite clear :) rsync for image (large) files create a new file for every little change, that was the reason I started looking in to using dirty bitmaps. /Jd On 10/11/14, 1:13 AM, Kashyap Chamarthy wrote: > On Fri, Oct 10, 2014 at 07:32:06PM -0600, Eric Blake wrote: >> On 10/10/2014 11:37 AM, Jd wrote: >>> Hi >>>
