comment SolusVM with KVM and HVM disk limits
I have no experience with Xen specifically so I don't know. My assumption is that it would be similar.

comment SSD Software RAID Alignment Necessary?
That is correct - even if they put there metadata at the start of the block device alignment of the volumes they provide is maintained, but they don't know the underlying physical device so have to just assume that alignment is fine to start with.

comment SSD Software RAID Alignment Necessary?
If the block devices (whole disks, partitions, RAID volumes) your PVs are hosted in are correctly aligned, then all the LVs in the VGs using those PVs will be correctly aligned too as everything LVM does is done on 64KiB or 1MiB boundaries within those containers. If the block device holding a PV is misaligned though, everything in that PV will be misaligned.

comment OpenVPN UDP not connecting
As for UDP not working we need a little more info about the server's location (and network layout) and where you are trying to connect from. If the server is behind NAT then it may be that you have setup port forwarding for the relevant port using TCP but have not added a forwarding rule for UDP. It could also be that your client location layers of NAT that don't track and translate UDP correctly (I could name at least one mobile provider in the UK which is setup this way).

comment OpenVPN UDP not connecting
You should be more precise with your analysis of the performance difference. Include if you can typical speed, latency, and packet loss both with and without the VPN. My first suspicion would be high latency and/or packet loss which can cause significant problems for TCP-over-TCP-based-VPN (I see issues of this nature over mobile phone based links for instance). Using UDP for the VPN layer can reduce this significantly effect as you don't have two layers of TCP's congestion control confusing each other.

comment Why is it good to have website content files on a separate drive other than system (OS) drive?
It is unlikely to crash but it may stop things being logged as there is no room to expand log files, and can cause updates to fail in a way that makes them hard to retry. It is considered a security issue because it could be used as part of a denial of service attack our to make other attacks harder to see/diagnose because of the logining issue.

comment will hosting provider have access to my dedicated server?
That depends on what you call cheap. It isn't unusual to see dedicated server offers below $30/mo, sometimes below $20 (though usually with an upfront setup fee). It'll not be high spec (an atom or old core2, maybe only 80gb storage, and so fourth), but it'll be real hardware you are renting. For most uses a VPS will give better value, but if you need dedicated kit (to guarantee no IO contention perhaps, or to guarantee stable predictable a performance generally, or so you can encrypt your storage as securely as possible, and so fourth)

comment Start program on computer startup when nobody is logged on and show the window when someone does log on (OS: Windows)
@Marcus: The limits on who can do what and when are intended to stop certain abuses. Unfortunately they do sometimes cause inconvenience for genuine attempts to do things right, but sometimes such compromises need to be made. If you have a suggestion that might improve the situation (protecting the site at least as well but inconveniencing genuine users less) it would be a better idea to raise the thought via a relevant "meta" site (meta.serverfault.com, meta.stackoverflow.com) instead of complaining in a comment that the site runners are very unlikely to see.
