[Xen-devel] [PATCH 1 of 2] Remus: use imqebt instead of ebtables

Remus: use imqebt instead of ebtables

I added a standalone IMQ-aware ebtables version in the initial Remus submission,
but forgot to actually activate it. This fixes that oversight.

Remus: ensure kernel modules are built before attempting to install them

make tools seems to skip straight to the install target.

I always do this steps manually... at hand...

Thanks...

Re: [Xen-devel] [PATCH 2 of 2] Remus: ensure kernel modules are built before attempting to install them

Hi:
It''s so greate to know that you have added this.
I can "xm create" pv guest successfully using:
disk=[
''tap:remus:server2:9000|aio:/home/ninja/img/test/paraV.img,hda1,w''
]

However, when I updated my xen-unstable version from 20570: aa01a13d750b to
20844.I encountered a problem seems very strange:

[root@server1 test]# xm create vm1.cfg
Using config file "./vm1.cfg".
Error: Device 769 (tap) could not be connected.
server2:9000|aio:/home/ninja/img/test/paraV.img does
not exist

What I can ensure is that this is not
If I remove "remus:server2:9000| ", I can create the pv normally using
"disk=[ ''tap:aio:/home/ninja/img/test/paraV.img,hda1,w''
]". So it seems that
I make something wrong with the "remus:server2:9000| ". Yet I did
successfully create a pv using the same configuration in a previous version
of xen-unstable(I''m not quite sure if there is a bug been imported into
the
later version since 20570).

Do I miss something? Thanks for pointed out.

This is my configuration file:
  1 kernel="/boot/vmlinuz-2.6.18.8-xen"
  2 ramdisk="/boot/initrd-2.6.18.8-xen.img"
  3 memory=256
  4 name="ParaOS"
  5 vcpus=1
  6 vif=[ '''' ]
  7 #vif = [ ''mac=00:16:3e:00:00:11, bridge=xenbr0'' ]
  8 ip="192.168.226.217"
  9 netmask="255.255.255.0"
 10 gateway="192.168.226.1"
 11 #disk=[ ''tap:aio:/home/ninja/img/test/paraV.img,hda1,w'' ]
 12 disk=[
''tap:remus:server2:9000|aio:/home/ninja/img/test/paraV.img,hda1,w''
]
 13 root="/dev/hda1 ro"

"server2" is the name of backup server, "9000" is the
intended port
and "/home/ninja/img/test/paraV.img" is the location of my image.

The error was oringiated from the function of "waitForDevice" in
xen/xend/server/DevController.py
the status of waiting is "Error" and the vm imediately destroy itself
which
seems caused by it hasn''t waited the "tap 769"(device ID
which listed in
xend.log as below).

the error info is at line 165 of DevController.py
157         elif status == Error:
158             self.destroyDevice(devid, False)
159             if err is None:
160                 raise VmError("Device %s (%s) could not be connected.
"
161                               "Backend device not found." %
162                               (devid, self.deviceClass))
163             else:
164                 raise VmError("Device %s (%s) could not be connected.
"
165                               "%s" % (devid, self.deviceClass,
err))

the "err"  in VmError above is produced by function
"waitForBackend" in
DevController.py too.
559             err = xstransact.Read(backpath, HOTPLUG_ERROR_NODE)
which I print out and get the value of backpath:
backpath:/local/domain/0/backend/tap/18/769.
I don''t know why xstransact.Read failed here.

Is it a name resolvation problem of remus, or guestOS version specific
problem(my pv is rhel5.3),

or just a configuration problem or anything else? I''m stunted.hope
someone
can give me any advice to step further.
