Re: [Libguestfs] supermin-helper: ext2: parent directory not found: /mnt/bigdata/var: File not found by ext2_lookup

I did what you said, and it passed that point. But I had another error. Maybe is not related.

I will run as you said.

Failed to connect to virtio-serial channel.

This is a fatal error and the appliance will now exit.

Usually this error is caused by either QEMU or the appliance
kernel not supporting the vmchannel method that the
libguestfs library chose to use.  Please run
'libguestfs-test-tool' and provide the complete, unedited
output to the libguestfs developers, either in a bug report
or on the libguestfs redhat com mailing list.

Hello,

I've found a problem running libguestfs on my system.

The system has /var mounted with a symbolic link to /mnt/bigdata/var

Any help here?
This is a bug, basically.

You could try to work around it by creating a file
/usr/lib/guestfs/supermin.d/00-dir containing the following lines:

----------------------------------------------------------------------
/
/mnt
/mnt/bigdata
/mnt/bigdata/var
----------------------------------------------------------------------

(not including the dashes).

If that doesn't work, take the supermin-helper command that is printed
in the debug output, and try adding -v -v -v to the command.  That
should make it print plenty of debug.  For example
libguestfs-test-tool prints:

   libguestfs: command: run: /usr/bin/supermin-helper
   libguestfs: command: run: \ --verbose
   libguestfs: command: run: \ --copy-kernel
   libguestfs: command: run: \ -f ext2
   libguestfs: command: run: \ --host-cpu x86_64
   libguestfs: command: run: \ /usr/lib64/guestfs/supermin.d
   libguestfs: command: run: \ --output-kernel /var/tmp/guestfs.pGpWYN/kernel
   libguestfs: command: run: \ --output-initrd /var/tmp/guestfs.pGpWYN/initrd
   libguestfs: command: run: \ --output-appliance /var/tmp/guestfs.pGpWYN/root

I run:

   supermin-helper -v -v -v --verbose --copy-kernel -f ext2 --host-cpu x86_64 /usr/lib64/guestfs/supermin.d /tmp/kernel --output-kernel /tmp/kernel --output-initrd /tmp/initrd --output-appliance /tmp/appliance

Rich.
