RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Debug info about converting windows with unclean file system

Description
Improve the error info when converting windows guest with unclean file system

Version:
virt-v2v-1.27.53-1.1.el7.x86_64
libguestfs-winsupport-7.1-4.el7.x86_64
libguestfs-1.27.53-1.1.el7.x86_64
virtio-win-1.7.2-1.el7.noarch

How reproducible:
100%

Steps to Reproduce:
1.Use virt-v2v to convert a windows guest which has an unclean file system.
# virt-v2v -ic xen+ssh://10.66.106.64 -os default xen-hvm-win8-i386 -of raw
[   0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 xen-hvm-win8-i386
[  16.0] Creating an overlay to protect the source from being modified
[  30.0] Opening the overlay
[  52.0] Initializing the target -o libvirt -os default
[  52.0] Inspecting the overlay
mount: /dev/sda2 on / (options: ''): The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sda2': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option. (ignored)
virt-v2v: error: libguestfs error: case_sensitive_path: 
case_sensitive_path_stub: you must call 'mount' first to mount the root 
filesystem

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]


Actual results：
error info shows as below,which is not so clear and friendly.
mount: /dev/sda2 on / (options: ''): The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sda2': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option. (ignored)
virt-v2v: error: libguestfs error: case_sensitive_path: 
case_sensitive_path_stub: you must call 'mount' first to mount the root 
filesystem

Expected results:
Improve the error info,especally the error info throw from virt-v2v.

Comment 2 Richard W.M. Jones 2014-09-24 17:50:29 UTC 
Should be fixed in >= 1.27.54:

Comment 4 tingting zheng 2014-09-25 05:45:29 UTC 
Tested with:
libguestfs-1.27.54-1.1.el7.x86_64
virt-v2v-1.27.54-1.1.el7.x86_64

# virt-v2v -ic xen+ssh://10.66.106.64 -os default xen-hvm-win8-i386 -of raw
[   0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 xen-hvm-win8-i386
[  16.0] Creating an overlay to protect the source from being modified
[  30.0] Opening the overlay
[  52.0] Initializing the target -o libvirt -os default
[  52.0] Inspecting the overlay
virt-v2v: error: unable to mount the disk image for writing. This has 
probably happened because Windows Hibernation or Fast Restart is being used 
in this guest. You have to disable this (in the guest) in order to use 
virt-v2v.

Original error message: mount: /dev/sda2 on / (options: ''): The disk 
contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sda2': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]

The error info has been improved,so move the bug to VERIFIED.
