Unknown protocol 'openvstorage'

[yongshengma]

Hello,

I cloned and compiled this project in spite of a warning:

  CC    vl.o
vl.c: In function ‘main’:
vl.c:2778:5: warning: ‘g_mem_set_vtable’ is deprecated [-Wdeprecated-declarations]
     g_mem_set_vtable(&mem_trace);

Makefile:400: recipe for target 'install' failed

qem

I commented them in install part of Makefile as these files do not exist at all. Continue.

Convert a qcow2 image into vdisk:
qemu-img convert cirrus.qcow2 openvstorage+tcp:192.168.20.32:26203/cirrus
It works fine. Go to next.

Start VM:

root@Node-32:~# /usr/local/bin/qemu-system-x86_64 -drive file=openvstorage:cirrus,if=virtio,cache=none,format=raw

(process:26408): GLib-WARNING **: /build/glib2.0-7ZsPUq/glib2.0-2.48.2/./glib/gmem.c:483: custom memory allocation vtable not supported
qemu-system-x86_64: -drive file=openvstorage:cirrus,if=virtio,cache=none,format=raw: Unknown protocol 'openvstorage'

Do I miss something?

Best regards,
Yongsheng

[yongshengma]

Sorry. I ran qemu-img convert before I compiled this project, so it should be located in /usr/bin instead of /usr/local/bin. Should I remove the previous qemu pkgs first?

[cnanakos]

@yongshengma we already provide packages for qemu, otherwise you need to use the correct qemu binary produced from your compilation.

[yongshengma]

But qemu-system-x86_64 with openvstorage tag didn't work before. That's why I built it this time. The repo I used to install qemu:
echo "deb http://apt.openvstorage.com fargo-updates-1 main" > /etc/apt/sources.list.d/ovsaptrepo.list

Same issue in previous env:

This message only modules from the same build can be loaded make me compile it.

[cnanakos]

@yongshengma please compile from the feature/for_16.04_v2.5 branch.

[yongshengma]

Hi @cnanakos

I compiled feature/for_16.04_v2.5 branch and made install but i got the same issue as before. Let me re-summarize a bit and just want to make sure.

/usr/bin/ vs /usr/local/bin/
and

1. The qemu-* files provided by deb packages from openvstorage repo are installed in /usr/bin/
2. The qemu-* files made from master or branch feature/for_16.04_v2.5 are installed in /usr/local/bin/

qemu-img

3. /usr/bin/qemu-img convert cirrus.qcow2 openvstorage+tcp:192.168.122.32:26203/cirrus still works as before.
4. '/usr/local/bin/qemu-img convert cirrus.qcow2 openvstorage+tcp:192.168.122.32:26203/cirrus' still gives the error:
   qemu-img: Unknown protocol 'openvstorage+tcp'

qemu-system-x86_64

5. /usr/bin/qemu-system-x86_64 -drive file=openvstorage+tcp:192.168.122.32:26203/cirrus,if=virtio,cache=none,format=raw still failed:
