Patches posted: https://www.redhat.com/archives/libguestfs/2015-August/msg00098.html https://www.redhat.com/archives/libguestfs/2015-August/msg00099.html Moving to RHEL 7.3 since the bug isn't really very serious. Upstream commits: 66daad38f37c8975c4b6bcb760094cf4490fef14 42b6bb12dcbc5103044a9099d71f17a82009e7de Since I need to do another build of libguestfs today because of a regression, might as well take this bug for RHEL 7.2. Tested the bug with:
virt-v2v-1.28.1-1.51.el7.x86_64
Steps:
1.Use virt-v2v to convert guest with -oa preallocated -of qcow2.
# virt-v2v -ic xen+ssh://10.66.106.64 -os default -oa preallocated xen-hvm-rhel7.1-x86_64 -of qcow2 -on qcow2-preallocated
[ 0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 xen-hvm-rhel7.1-x86_64
[ 0.0] Creating an overlay to protect the source from being modified
[ 1.0] Opening the overlay
[ 8.0] Initializing the target -o libvirt -os default
[ 8.0] Inspecting the overlay
[ 31.0] Checking for sufficient free disk space in the guest
[ 31.0] Estimating space required on target for each disk
[ 31.0] Converting Red Hat Enterprise Linux Server release 7.1 (Maipo) to run on KVM
virt-v2v: This guest has virtio drivers installed.
[ 140.0] Mapping filesystem data to avoid copying unused and blank areas
[ 140.0] Closing the overlay
[ 142.0] Checking if the guest needs BIOS or UEFI to boot
[ 142.0] Copying disk 1/1 to /var/lib/libvirt/images/qcow2-preallocated-sda (qcow2)
(100.00/100%)
[ 449.0] Creating output metadata
Pool default refreshed
Domain qcow2-preallocated defined from /tmp/v2vlibvirt953164.xml
[ 451.0] Finishing off
2.After conversion,check the disk,it's fully peallocated.
# ll -lsh qcow2-preallocated-sda
5.9G -rw-r--r--. 1 root root 5.9G Sep 2 17:59 qcow2-preallocated-sda
# qemu-img info qcow2-preallocated-sda
image: qcow2-preallocated-sda
file format: qcow2
virtual size: 5.9G (6291456000 bytes)
disk size: 5.9G
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
