According to the logs it seems to fail without error around 2% into
the disk copy:
qemu-img 'convert' '-p' '-n' '-f' 'qcow2' '-O' 'raw' '/var/tmp/v2vovl4d64d3.qcow2' '/var/tmp/mpt3sas-sda'
(0.00/100%)
(1.00/100%)
(2.00/100%)
But the error report says ...
> 3.Input info and start convert but the conversion is failed during
> opening overlay,details pls refer to log "virt-p2v-mpt3sas-1.38.2-1"
I think you've got the wrong log files?
I uploaded two logs, one is "virt-p2v-mpt3sas-1.38.2-1" which is the detailed log for the bug, the other one is "virt-p2v-mpt3sas-1.36.10-1" which is the log for additional info's scenario, I also upload a new log "virt-p2v-mpt3sas-1.38.2-1-log" for your reference, thanks Created attachment 1451948 [details]

Oh indeed you did, thanks. The error is .. strange. It fails at: [ 1.994948] Error: Driver 'pcspkr' is already registered, aborting... libguestfs: child_cleanup: 0x28ba790: child process died The error is not the pcspkr one, because it appears in other logs. In normal output we might expect to see other drivers being loaded such as this one: [ 0.722479] alg: No test for __gcm-aes-aesni (__driver-gcm-aes-aesni) [ 0.723225] alg: No test for __generic-gcm-aes-aesni (__driver-generic-gcm-aes-aesni) This smells of a qemu crashing bug because of a problem with emulating an AES-NI instruction. Is it possible that you still have the file /var/log/libvirt/qemu//guestfs-rcm8meh2boll2jnc.log still around from that run? It may contain information from why qemu crashed. If that file doesn't have any useful information, then perhaps there was a core dump which was collected by coredumpctl?

virt-p2v-mpt3sas-qemu-kvm-rhev-2.12.0-8-log
Getting back to basics, I found a very easy way to reproduce the original bug by creating a guest with an irregular size: $ virt-builder fedora-27 --size=7234567890b $ virt-v2v -i disk fedora-27.img -o null ... [ 0.4] Opening the overlay virt-v2v: error: libguestfs error: guestfs_launch failed, see earlier error messages And if you look in the ~/.cache/libvirt/qemu/log/guestfs*.log file: qemu-system-x86_64: /builddir/build/BUILD/qemu-2.12.0/block/io.c:1098: bdrv_co_do_copy_on_readv: Assertion `skip_bytes < pnum' failed. I then tried different versions of qemu: upstream qemu from git (18a398f6) => WORKING. qemu-kvm-rhev-2.10.0-21.el7_5.4.x86_64 => WORKING. qemu-kvm-rhev-2.12.0-3.el7.x86_64 => BUG REPRODUCED. qemu-kvm-rhev-2.12.0-8.el7.x86_64 => WORKING. I would say that the bug has been fixed in qemu-kvm, and the bug you are seeing is a new problem.

(You need to look at > guestfs-rcm8meh2boll2jnc.log) I just found below info named "guestfs-xxx" in virt-v2v-conversion-log.txt, but didn't find info "guestfs-rcm8meh2boll2jnc.log" # cat virt-p2v-mpt3sas-qemu-kvm-rhev-2.12.0-8/virt-v2v-conversion-log.txt |grep guestfs- libguestfs: guest random name = guestfs-t3x85ya76lmwth9y ..... # cat virt-p2v-mpt3sas-qemu-kvm-rhev-2.12.0-8/virt-v2v-conversion-log.txt |grep guestfs-rcm8m nothing Hi rjones, Do I need to open a new bug for the new problem?
