Re: [Libguestfs] oVirt import from VMware

Thanks for sending the disk image across. With latest libguestfs and guestfs-tools I am able to inspect the image fine: $ rpm -q guestfs-tools libguestfs guestfs-tools-1.47.2-1.fc35.x86_64 libguestfs-1.45.6-6.fc35.x86_64 $ tar xf SoftdriveTest.ova SoftdriveTest2-disk1.vmdk $ virt-inspector -a SoftdriveTest2-disk1.vmdk <?xml version="1.0"?> <operatingsystems> <operatingsystem> <root>/dev/sda2</root> <name>windows</name> <arch>x86_64</arch> <distro>windows</distro> <product_name>Windows 10 Home</product_name> <product_variant>Client</product_variant> <major_version>10</major_version> <minor_version>0</minor_version> <windows_systemroot>/Windows</windows_systemroot> <windows_current_control_set>ControlSet001</windows_current_control_set> <osinfo>win10</osinfo> <mountpoints> <mountpoint dev="/dev/sda2">/</mountpoint> </mountpoints> ... Recent virt-v2v gets further, but hits an issue because the guest is using Fast Restart: $ rpm -q virt-v2v virt-v2v-1.45.1-1.fc35.x86_64 $ virt-v2v -i ova SoftdriveTest.ova -o null [ 0.0] Opening the source -i ova SoftdriveTest.ova [ 166.6] Creating an overlay to protect the source from being modified [ 166.7] Opening the overlay [ 173.0] Inspecting the overlay virt-v2v: error: filesystem was mounted read-only, even though we asked for it to be mounted read-write. This usually means that the filesystem was not cleanly unmounted. Possible causes include trying to convert a guest which is running, or using Windows Hibernation or Fast Restart. (https://libguestfs.org/virt-v2v.1.html#windows-8-fast-startup-is-incompat...) Looking at the detailed log, the inspection step was fine. Therefore I think it should work fine if Fast Restart was disabled before conversion. I went back to the old version of libguestfs you're using (1.40) virt-inspector shows pretty similar output to your virt-v2v log. However when I looked closer I found that guestfish cannot mount the /dev/sda2 partition from this disk at all. I'm not at all clear why. I guess it might be fast restart or something else (too old ntfs-3g?) Anyway since it works with recent libguestfs/virt-v2v, I would suggest upgrading to a later version and disabling Fast Restart in Windows guests before conversion, which together should solve the problem.
