LocalCopy was previously only using stat to determine the size of a source disk. If that source disk was a block device it would return 4k. Amongst other problems, this resulted in disks which would not import into RHEV. --- lib/Sys/VirtV2V/Transfer/LocalCopy.pm | 32 +++++++++++++++++++++++++++++++- 1 files changed, 31 insertions(+), 1 deletions(-) diff --git

Sadly, there are elements (hello "gentoo"!) that, during the cleanup.d phase, wipe out almost everything in the /tmp of the guest, including the /tmp/aux where virt-dib mounts the auxiliary data. Since that removal excludes things starting with "in_target" (mostly to avoid wiping the "in_target.d" that disk-image-create itself sets up, then rename our "aux"

Thanks for the work-around. Using "blockdev --flushbufs $dev" does indeed make parted behave the same with dm-backed storage as with other devices.

Hello list, upon upgrading from libvirt v5.9.0 -> v5.10.0, libvirt started calling qemu differently causing the VM operating system to not be found. I'm wondering whether I'm chasing a bug, or have to otherwise fix my domain config (created by virt-manager). To start with, I have a Windows 7 domain based on the following images: windows7-base.qcow2: QEMU QCOW2 Image (v3),

The real sudo does it as well, and leaving them when preserving the environment (-E) maybe breaks the applications, as e.g. chroot will have a TMPDIR path pointing outside of it. --- dib/dib.ml | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/dib/dib.ml b/dib/dib.ml index df83ba1..d15cd19 100644 --- a/dib/dib.ml +++ b/dib/dib.ml @@ -301,6 +301,11 @@ if [ -z \"$preserve_env\" ];

Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'
