Re: [Libguestfs] virt-v2v F18 guest on F18 failure
Hi,Richard
Recently I met this error when I execute virt-v2v on rhel7,but I can not reproduce on
another machine with even the same packages.
# LIBGUESTFS_ATTACH_METHOD=appliance virt-v2v -ic xen+ssh://10.66.72.23 -os default

I think I've *discounted* IDE as a potential problem:
$ rm /tmp/test1.img
$ truncate -s1G /tmp/test1.img
$ guestfish <<EOF
set-attach-method appliance
add-drive-opts /tmp/test1.img iface:ide readonly:true
run
mount /dev/sda /
EOF
libguestfs: error: mount: /dev/sda on / (options: ''): mount: wrong fs type, bad
option, bad superblock on /dev/sda,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
(the expected error)
vs:
$ guestfish <<EOF
set-attach-method appliance
add-drive-opts /tmp/test1.img iface:ide readonly:true
run
mkfs ext2 /dev/sda
mount /dev/sda /
EOF
(no error)
Also tried:
- Adding name:vda
- Running isoinfo-device before the mount.
- Running vfs-type before the mount.
I still couldn't reproduce this.
Rich.
