ERROR: Java process not running. Try restarting the SSVM.

Dear all,

I am running ACS 4.2.0 in our test environment and after restarting the KVM
host, I am not able to get SSVM agent up and running, despite destroying
and recreating it.

The problem is similar to what Mike Tutkowsi reported on below thread, same
symptoms but different cloud.out stack error message:

http://comments.gmane.org/gmane.comp.apache.cloudstack.devel/28827

I can SSH into SSVM but unable to start the Java agent. SSVM health check
result shows two error:
- Unable to connect NFS (wrong IP detected); and
- Unable to start Java.

Unable to connect NFS is because wrong IP is detected for the NFS ip. I can
manually mount the NFS server IP using correct IP.

Result:

I did some research and found that this could be due to the use of mixed
OSS and non-OSS package, but I installed both the management and agent from
the OSS package.

There's also mentioned that it could be due to systemvm.iso file, I have
tried to re-register the system VM template using cloud-install-sys-tmplt,
delete and restore the systemvm.iso file from
/usr/share/cloudstack-common/vms folder, but none helped.

The strange thing is that it was working before, I only restarted the KVM
host and now the problem happened. I even tried to backup the DB and do a
clean reinstallation of ACS 4.2.0 from scratch, and the problem still
persists!

Any pointer is highly appreciated.

Thank you.

Hi,


Is there a reason you're testing 4.2 and not 4.8?


4.2 was released in mid 2013, so is very old.

I did some research and found that this could be due to the use of mixed
OSS and non-OSS package, but I installed both the management and agent from
the OSS package.

There's also mentioned that it could be due to systemvm.iso file, I have
tried to re-register the system VM template using cloud-install-sys-tmplt,
delete and restore the systemvm.iso file from
/usr/share/cloudstack-common/vms folder, but none helped.

The strange thing is that it was working before, I only restarted the KVM
host and now the problem happened. I even tried to backup the DB and do a
clean reinstallation of ACS 4.2.0 from scratch, and the problem still
persists!

Any pointer is highly appreciated.

Thank you.
