Doc Text:
*virt-v2v* can convert Windows guests with corrupted or damaged Windows registries Previously, the *hivex* library used by *libguestfs* to manipulate the Windows registry could not handle corrupted registries. Consequently, the *virt-v2v* utility was not able to convert Windows guests with corrupted or damaged Windows registries. With this update, *libguestfs* configures *hivex* to be less strict when reading the Windows registry. As a result, *virt-v2v* can now convert most Windows guests with corrupted or damaged Windows registries.

Description tingting zheng 2016-02-25 09:47:21 UTC
Description of problem:
Fail to convert some win10 guests from esx,but some one can be converted successfully.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Use virt-v2v to convert win10 i386 from esx 5.1,it fails with error:
virt-v2v: error: libguestfs error: hivex_open: hivex failed to open 
/Windows/System32/config/SOFTWARE: Operation not supported

2.log info:

Actual results:
As description.

Expected results:
Win 10 can be converted successfully.

Additional info:

Comment 4 Richard W.M. Jones 2016-06-22 15:11:58 UTC
The actual error is:

hivex: hivex_open: returning ENOTSUP because: SOFTWARE: trailing garbage at end of file (at 0x2084000, after 7639 pages)
hivex_open: SOFTWARE: Operation not supported

Similar to bug 739029.

Anyway, this requires a change to hivex to make it more lax (like
Windows itself) when processing corrupt registries.

Since hivex is not on the ACL for RHEL 7.3, this conveniently means
we can defer this bug to 7.4.

Comment 5 Richard W.M. Jones 2016-07-06 10:28:26 UTC
*** Bug 1230414 has been marked as a duplicate of this bug. ***

Comment 6 Richard W.M. Jones 2017-02-16 14:24:59 UTC
Defer to RHEL 7.5.  Someone is in fact working on this problem
upstream, see:

Comment 7 Richard W.M. Jones 2017-02-17 10:25:33 UTC
The hivex patches were completed unexpectedly quickly.  I have
posted patches for libguestfs to use them.

This will require changes to hivex too.


Comment 9 mxie@redhat.com 2017-04-01 02:33:25 UTC
Verify the bug with builds:

1.Build auto job:converting win10(i386 and x86_64) guests from ESXi5.1/5.5/6.0 to libvirt by virt-v2v

rhel means that run the testing with qemu-kvm
rhev means that run the testing with qemu-kvm-rhev

All win10 guests could be converted successfully and checkpoints are passed, details pls refer to below jobs

So the bug has been fixed, move the bug from ON_QA to VERIFIED
