[Qemu-devel] [Bug 1071236] [NEW] creating qcow2 image with preallocation fails if size >=4G |
Date: |
Thu, 25 Oct 2012 09:43:09 -0000 |
Public bug reported:
Steps to reproduce:
1. run> qemu-img create -f qcow2 -o cluster_size=512,preallocation=metadata
disk.img 4G
Reproducible:
Always
Configuration:
Gentoo Linux 3.4.9, 64b
latest qemu available from portage (afaik this is pulled from the git repo)
Possible workarounds:
1. ommit preallocation=
2. increase cluster_size
3. reduce the image size
Although workarounds are available, it is still a bug that could (and
should) be fixed.
