Package: libssh-4
Version: 0.11.1-1
Severity: important
Tags: upstream
Control: affects -1 = qemu-block-extra qemu guestmount guestfish
Dear Maintainer,
With libssh-4 (0.11.1) qemu fails to access remote disk images via
ssh. After downgrading to libssh-4 (0.10.6-3) the VM starts again as
expected.
To reproduce the issue on a amd64 machine
* make sure you have sshd running
* make sure sure can ssh to localhost
* make sure you have ssh-agent running and preloaded with your private key
* apt install qemu-system-x86
* download and unpack the amd64-pc disk image from
https://people.debian.org/~gio/dqib/
* cd to the dqib_amd64-pc directory resulting from unpacking
* run
qemu-system-x86_64 -machine 'pc' -enable-kvm -m 1G \
-drive
file=ssh://<user>@localhost/home/<user>/.../dqib_amd64-pc/image.qcow2 \
-kernel kernel -initrd initrd -nographic -append "root=LABEL=rootfs
console=ttyS0"
With libssh-4 (0.11.1-1) qemu-system-x86_64 exits with error message
Could not read image for determining its format: Input/output error
With libssh-4 (0.10-6-3) the VM starts up.
For guestfish and guestmount downgrading libssh-4 does not help.
Running questmount with libssh-4 (0.11.1-1)
guestmount -i -a
ssh://<user>@localhost/home/<user>/.../dqib_amd64-pc/image.qcow2 <mount point>
returns (amongst others)
libguestfs: error: appliance closed the connection unexpectedly.
Running questmount with libssh-4 (0.10-6-3) returns
guestmount: /lib/x86_64-linux-gnu/libssh.so.4: version `LIBSSH_4_10_0' not
found (required by /lib/x86_64-linux-gnu/libvirt.so.0)
The attached report, generated using abi-compliance-checker, reveals
problematic changes to data types
ssh_callbacks_struct, ssh_channel_callbacks_struct in callbacks.h
sftp_session_struct in sftp.h
Hope this helps to fix the issue.
Sven
