comment Firewall throughput
Bandwidth will limit theoretical value of max number of packets per second. The number of PPS will be lower as it will be affected by latencies for storing and forwarding the packet, jitter(if your source is not perfectly in sync with the switch, some packets will get discarded or queued).

comment In a software RAID1, why does tune2fs -c 0 /dev/sda1 not throw an error but change is not seen in tune2fs -l /dev/sda1?
No, the UUID should be different. Could you please add the output of lsblk --output NAME,KNAME,MAJ:MIN,FSTYPE,UUID

comment java installed but not working (dependency issue??)
I think it is a script. Try to see the contents with less, or use file /usr/lib/jvm/jdk1.8.0_40/bin/java

you can run ldd /usr/lib/jvm/jdk1.8.0_40/bin/java to see which libraries are linked dynamically and used at startup.

comment Create tar on remote server and send it back over SSH
Please also note that I removed -C in ssh, you do not want gzip compression for data compressed with bzip2.

comment Server crashes with “huge task timeout”
Canonically, the console is the primary terminal where the kernel messages are printed. It could be a serial tty.

Access to the console, means the terminal where you can configure the BIOS and see the kernel boot messages.

19GB active memory average - I think soon you will need to ad more memory to the VM and to MySQL too.

The disk I/O is very low after reboot. I was wondering why is so high before reboot?

The memory graphs of Munin would be interesting then. If you have Disk I/O would be great too.

%steal is CPU requested by your VM and not given because another VM was scheduled to run. The higher it is the slower will be your VM.

Could you please explain the crashing behavior? Is it a core dump, a kernel panic? Resource starvation? OOM Killer? KVM crash?
