[Sheepdog] [ANNOUNCE] Sheepdog 0.2.0 released

[Serge Leschinsky]

Kazutaka,

One possible issue with 'qemu-img convert' was found (see at the end of message).

So, the test setup is:

Tests:

===================================================================
 > - live migration
 >
 > A is the source host, B is the destination host, 'test' is the vdi name of 
Sheepdog:
 >
 > 1. Start the VM on A
 >
 >   $ qemu sheepdog:test
 >
 > 2. Start the VM on B with '-incoming' option
 >
 >   $ qemu sheepdog:test -incoming tcp:0:4444
 >
 > 3. Do migration in the qemu monitor on A
 >
 >   (qemu) migrate -d tcp:B:4444
 >
 > See also:

Migration was flawless!


===================================================================

 > - run VMs outside the cluster
 >
 > A is one of the Sheepdog nodes, 'test' is the vdi name of Sheepdog.
 > Then run:
 >
 >   $ qemu sheepdog:A:7000:test
 >
 > '7000' is a port number the sheep daemon uses.

  - from the 4th node the following VM has been created (boot from Live-CD):

qemu-kvm -name DL  -smp 1  -m 256 -vnc :07 -localtime \
-usb -usbdevice tablet -net nic,macaddr=52:54:1a:89:90:09,model=virtio,vlan= \
-net tap,ifname=tap07,vlan=  -pidfile /var/run/kvm/bob.pid  \
-monitor unix:/var/run/kvm/bob.mon,server,nowait \
-boot d \
-hda sheepdog:192.168.177.25:7000:mumu  \
-drive index=1,media=cdrom,if=ide,file=/backups/kvm-images/bootcd.iso \
-clock unix -daemonize -enable-kvm

Everything is OK.

  - Install the system on hda (sheepdog:192.168.177.25:7000:mumu)

Everything is OK.

- Boot the VM from sheepdog VDI and connect 2 other VDIs (from different nodes)

qemu-kvm -name DL  -smp 1  -m 256 -vnc :07 -localtime \
-usb -usbdevice tablet -net nic,macaddr=52:54:1a:89:90:09,model=virtio,vlan= \
-net tap,ifname=tap07,vlan=  -pidfile /var/run/kvm/bob.pid  \
-monitor unix:/var/run/kvm/bob.mon,server,nowait \
-boot c \
-hda sheepdog:192.168.177.25:7000:mumu \
-hdb sheepdog:192.168.177.35:7000:kuku \
-hdc sheepdog:192.168.177.34:7000:nunu \
-clock unix -daemonize -enable-kvm

Everything is OK.


- qemu-img convert sheepdog:192.168.177.35:7000:kuku  /tmp/ttt.img

Everything is OK, I can boot from /tmp/ttt.img


- qemu-img convert  /tmp/ttt.img sheepdog:192.168.177.35:7000:tutu

Oops...

qemu-img convert  /tmp/ttt.img sheepdog:192.168.177.35:7000:tutu
failed connect to localhost:7000

qemu-img: sheepdog:192.168.177.35:7000:tutu: error while converting raw:
