similar to: import qcow with snapshots

Hi guys, I had to move to the new laptop week ago and I screw migration of my virtual machines. I recovered my virtual machines on the new laptop (virsh define) using the backed up xml files, but I am missing any file with metadata about snapshots. The original storage is cleaned so I cannot take these files anymore. Using qemu-info I can see my snapshots inside the qcow images, but libvirt

Hi,guys, During a HVM''s running which take a qcow format image file as its own virtual disk, the qcow image file will be always read.In the situation that its qcow format image is based on a raw format image, if nesethe backingfile ,just that raw format image file,would be read .my purpose is to cache the data that is read from the backingfile when the hvm is running . Now what I concern

Hi, I want to ask if anyone of you is familiar with QCOW and has used this with xen? I''ve googled a bit about and could''nt really find out if it''s a good choice or not. Has anyone experience with usage in xen and can say something about performance and snapshot usability? Thanks in advance, Alex _______________________________________________ Xen-users mailing

Dear,Beg for your help. I am really puzzled with this problem.HVM domain can not boot up with Qcow incremental image(using command: qcow-create size incremental_file original_Qcow_img_file), but it can boot up with the original Qcow disk image file. When using Qcow incremental image, the guest qemu window would disappear before loading grub, and `xm list` can not find this guest domain.The VM

Hi, Trying to understand the current state of affairs with QCOW support in Xen with the blktap driver. It''s been made clear that a deviation from QEMU''s implementation of QCOW has occurred and that the QCOW files used in Xen must be created with the associated Xen tools only (e.g. qcow-create) and that images between QEMU and Xen are not interchangeable. My first question is

Hi everyone, I'm posting here because I'm facing a kerberos authentication problem after the 2:4.13.17~dfsg-0ubuntu1.20.04.4 samba upgrade. The clients, win10, win11, win2016 cannot login to AD anymore. On server logs the authentication succeeded but in the Event Viewer on the client I have this error: Security-Kerberos The Kerberos client received a KRB_AP_ERR_MODIFIED error from the

For many months now we have been trying to create a file-backed qcow image with the qcow-create code. Each time we try to back a file with a qcow, it screams: *** buffer overflow detected ***: qcow-create terminated Below is the output from two different attempts and information about qcow-create. Any ideas/thoughts/help you can offer? Thank you for your help! -Eric [root@trogdor ~]#

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

Hello, This is a second post, with a trial which is different from the first one , in order to solve my blcok-attach problem. I tried the following two actions, according to the blktap readme: qcow-create 1000 qcowFile.img Creating file size 1048576000 Created cksum: 1813725440 then xm block-attach 0 tap:qcow:qcowFile.img /dev/xvda1 w 0 I see in the /var/log/xen/xend.log: [2007-03-13

Hi, i would like to use qcow2-sparse-images which point to a backup-file. After reading this: http://wiki.xensource.com/xenwiki/DmUserspace i figured out that this feature seems to be unsupported by the ubuntu 8.04 LTS kernel and xen-3.2.1. Is this a ubuntu-specific problem, or is it solved in Suse, Red Hat, XenSource, whatever? When i try to block-attach it, xm displays no error, but the

Hi, I ran into a strange behavior with libvirt snapshots. I have some vms running with thin-provisioned qcow2 disk images (libvirt 1.1.3 with fedora 20). * When I create a snapshot on the VM, the qcow file suddenly grows big, somewhat bigger than the maximum size of the disk. * When I delete the snapshot, the allocated disk space is not freed up, the qcow image remains the same size. However, if

Recently we had a try of stubdom, whose general status is good. One issue we found is with aio/sync blktap as backend, disk performance is obviously slower, and there are some IDE kernel error messages (like irq timeout) at boot time. Another issue (not stubdom specific) comes from blktap''s support for QCOW image which is based on a backing file. We never tried this configure

Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with
