[Libguestfs] Can I use virt-filesystem on a running VM?

Well, if I've run from kvm hypervisor this command with a live guest: virt-filesystems --long -h --all -a /home/storage-plus/myvm.qcow2 It outputs: `libguestfs: error: list_filesystems: parted exited with status 1: Error: Can't have a partition outside the disk!` But the very very sad of the story is that guest filesystem crashes: ene 05 21:23:22 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 25652400 ene 05 21:23:22 myvm.example.com kernel: XFS (dm-0): writeback error on sector 20430000 ene 05 21:23:22 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 25651200 ene 05 21:23:22 myvm.example.com kernel: XFS (dm-0): writeback error on sector 20428800 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 44519951 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 44519951 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 5222401 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 5231568 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 5232232 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 5237584 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 5262240 ene 05 21:23:27 myvm.example.com kernel: blk_update_request: I/O error, dev vda, sector 5379440 ene 05 21:23:27 myvm.example.com kernel: XFS (dm-0): metadata I/O error in "xlog_iodone" at daddr 0x257a20f len 64 error 5 ene 05 21:23:27 myvm.example.com kernel: XFS (dm-0): xfs_do_force_shutdown(0x2) called from line 1238 of file fs/xfs/xfs_log.c.
