similar to: Disk not bootable from yesterday resolved

Hi, In most cases we use image files as virtual disks under the full-virtualization situation.On the version 4.1.2 of xen,I do the following command: ############################################################ dd if=/dev/zero of=myraw.img bs=1M seek=8K count=1 #Before the command below I install the operating system in myraw.img qemu-img-xen create -b myraw.img -f qcow2 myqcow1.img 20000M

I am experimenting with the blockcopy command, and after figuring out how to integrate qemu-nbd, nbd-client and dumpxml/undefine/blockcopy/define/et. al. I have one remaining question: What's the point? The "replication" disk file is not, from what I can ascertain, bootable. I expect this operation to create a pristine copy of my source qcow2 file (at a given point in time)

Occasionally this test will choose a random seed which results in an all-zeroes disk. The test tries to convert this to a compressed qcow2 file, and fails because no compressed clusters are detected in the resulting file. This happens because qcow2 stores zero clusters with a special sparse representation, they are never stored compressed, so a disk with only zeroes in it will never contain

For raw, this allows "off" as a synonym for "sparse" (to make it consistent with qcow2). For qcow2, this allows "sparse" as a synonym for "off". It also adds qcow2 "full" preallocation, which is actually mapped to the qemu option "falloc" (see arguments about this on the qemu-devel mailing list, which we lost). This also updates the

Hi all, i created a script in PHP for create a virtual server with two QCOW2 discs … one is our system for installation and second is target system. After successfully instalation (create a blank Debian system, prepare all files and grub partitions) i need a restart virtual without a installation disk. If i use Virsh: detach-disk --domain debian-test2 --persistent --target vda reset

Hi! I was reading the Wiki about 'Live Disk Backup with Active Blockcommit, https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit and see that example shown seems to be using two different names for the same file.
