comment Allocated Memory difference in xen guests with Linux 2.6.18 and 2.6.32
On question 1, in the section below where you have the text "despite showing", you then go on to show that dmesg is reporting "500984k/524288k". That means "500984k is available out of 524288k total". The free command also shows 524288k total mem, as per your output.

Centos 6.3 is also RedHat based, so will be different from Debian based (Ubuntu). Additionally, Centos 6.3 probably has different defaults compiled into the kernel than either 5.7 or Ubuntu, so it makes sense that it is different.

comment Why does OS X spend one more packet to establish and close a TCP connection?
tcpdump is perfectly valid for looking at this. The information is not easier to access in wireshark if you have to 1) install a GUI, 2) install wireshark.

comment Reviewing firewall rules
RedSeal is more than just firewall rules, they do all kinds of stuff to help visualize your network security architecture, including determining if your current access control stance (implemented via firewalls, ACLs, etc.) is complaint with your desired company "policy" (or other standards, such as PCI-DSS, et al). As far as firewall rules go, they can analyze for a bunch of Best Practice checks, in addition to some firewall specific stuff such as unused rules, missing logging, etc. for a variety of different vendors.

comment How to restore Ubuntu server on a VMWare image after disk failure?
You probably need to mount specific partitions: "/dev/sdb3" or similar. Try "sudo fdisk -l /dev/sdb" to see what might be available.

comment How to restore Ubuntu server on a VMWare image after disk failure?
If you really have to "recover" it, i.e. make the actual same image bootable again, then yea, probably run the rescue process. Otherwise, just copy off your configs and data and you are all set (I've found that this tends to get much more reliable and consistent results, and I don't end up spending hours troubleshooting weird boot parameters and grub issues that I don't really understand.)

The answer to this question is "Yes". But a one word answer is too short for a real answer, so I'm suggesting that you elaborate on your question with details on why you think it might not work and what your actual question is.
