comment ESXI Snapshots on a CentOS VM
"Note : VMware recommends you to use NTP instead of VMware Tools periodic time synchronization. NTP is an industry standard and ensures accurate timekeeping in your guest."

comment ESXI Snapshots on a CentOS VM
Technically it is stored in which-ever virtualized hardware timekeeping device is being emulated. That information is saved to the hosts disk, yes.

comment ZFS: 3 devices: what's the difference between mirror and raidz2?
@cnst It suggests the same answer for your 3-disk mirror as your 1 data + 2 parity = N-2 failures.

comment ZFS: 3 devices: what's the difference between mirror and raidz2?
@StefanLasiewski I'm not sure I made a comparison to RAID5/6 in my comment. Are you suggesting that there is less overhead in calculating parity or data-from-parity than making 2 additional copies?

comment ZFS: 3 devices: what's the difference between mirror and raidz2?
So a 3 way mirror would keep 3 copies of any data, while a 3 disk raidz2 would keep 1 write and 2 parity calculations of each data? One would imagine the mirror would be fast relative to the parity calculations, especially in a failure scenario requiring a rebuild.

comment Is there a Windows equivalent of Unix 'CPU steal time'?
Still fascinated by this topic, I looked up a Windows 2003 machine running on ESXi 5.1, and it looks like CPU information is available to the guest about it's virtualized CPU state, specifically it's stolen time (referred to as just that on the guest), CPU shares, CPU limit, and CPU reservation. pic

comment Creating a public_html for a user on a Red Hat Linux Server
@Anti-Earth Once you gain some experience, you will find it logical to search configuration files (to check for things like pre-existing values or useful comments). Red Hat documents many beginner details like this in their docs and if you have a subscription, in their paid knowledge base.

comment Why does git remote repo only work as root?
Check the sshd or secure log (usually /var/log/) for clues. Common issues are incorrect permissions on ~/.ssh/ and ~/.ssh/authorized_keys. Is your key file really called my_key? You're going to want to explicitly specify it in your command with ssh -i [path/to/mykey]. Most modern open-ssh distributions have ssh-copy-id, a script which helps set proper permissions on target systems. If you are on Mac, it is available with Homebrew.

comment Why does git remote repo only work as root?
Is it possible you could summarize, in relative detail, what you've done so far? There is not enough currently to avoid questions like: do you have a git user on the remote system? Does the user have a valid password?
