RebootInstances does not seem to work

[Neil Soman]

This is with xen.

Here is the request:

This is with REST as well as SOAP.

  fix problem with forming downstream message for reboot instaces

[Neil Soman (neilsoman)]

The front end now conveys the operation correctly. However, the operation itself fails (this is Debian lenny + xen).

cc.log:

[Fri Apr 24 15:39:04 2009][028969][EUCADEBUG ] refresh_resources(): called
[Fri Apr 24 15:39:05 2009][032315][EUCAERROR ] ERROR: RebootInstanceInstance() could not be invoked (check NC
host, port, and credentials)
[Fri Apr 24 15:39:05 2009][032257][EUCAINFO ] call complete (pid/rc): 32315/1
[Fri Apr 24 15:39:05 2009][032257][EUCADEBUG ] RebootInstances(): done.

nc.log:

[Fri Apr 24 15:39:06 2009][009440][EUCAERROR ] ERROR: doRebootInstance() failed error=1
[Fri Apr 24 15:39:06 2009][009440][EUCAINFO ] doDescribeInstances() invoked

axis2c.log on the NC:

[Fri Apr 24 15:39:06 2009] [error] adb_ncRebootInstanceResponseType.c(1059) Nil value found in non-nillable property status

So there seem to be two issues.

-The CLC returns the instance id indicating that everything is okay.
-The operation itself fails.

[chris grzegorczyk (chris-grze)]

The CLC returns true if the instance ID exists, the user executing the command is the owner of the instance, and the cluster which is hosting the instance is valid (i.e., still exists). So this is the expected behaviour.

It looks like the underlying problem has to do with permissions (from httpd-nc_error_log):

Error: Most commands need root access. Please try again as root.

[chris grzegorczyk (chris-grze)]

Error: Most commands need root access. Please try again as root.

[Neil Soman (neilsoman)]

Nope, that log entry is unrelated (much earlier timestamp). The log entries that I've pointed out earlier seem to capture the problem.

[Dmitrii Zagorodnov (dmitrii)]

Replacing 'xm reboot' invocation with virDomainReboot() allows non-root operation with Xen.
