comment Ubuntu software raid on efi, how to boot off second drive?
But as I understand it, the entries in the EFI boot menu — the information that tells it to run grubx64.efi from a particular directory in the EFI system partition — include the GUID of the partition that contains the file. So even if you have identical partitions on two different disks, the EFI will only try to boot from one of them. You could try giving the partitions the same GUID, but that might cause further problems since they're expected to be unique.

That might work, as long as the RAID is set up in such a way that each individual partition looks like an ordinary valid filesystem to the EFI (which isn't aware of the RAID). Linux software RAID1 using superblock format 1.0 (superblock at the end) may work.

comment how to sign a binary in Linux?
However, the public key needs to be transmitted securely, or you're vulnerable to a man-in-the-middle attack. You'll probably want to include the public key in your device's ROM, so that it has a reliable copy to use for checking signatures on downloaded updates.

comment is there such a thing as a 'quick' format for ext4?
Technically this doesn't actually make the format go faster, but it lets you mount and use the filesystem while the format finishes in the background.

comment How to redirect (or Alias) jump page with Apache
Redirects don't actually take 8 seconds. That delay you see on some pages is added on purpose so that you have time to read the message.

comment Recover Linux vmdk VMware file
"Bad geometry, block count exceeds" sounds like your partition is too small: the size of the filesystem according to its superblock is larger than the size of the partition it's in. But since fsck finds the superblock at least you seem to have the partition's starting address correct, which is progress.

comment Recover Linux vmdk VMware file
@Jack, the VMDK itself isn't broken; its contents just aren't what you'd like. There should be no problem with attaching it to another VM. What won't work is VMware's feature for mounting a partition in a VMDK as a drive on the host.

comment How to bridge a range of public IPs to KVM virtual machines on Debian/Ubuntu
The "network is unreachable" message in this case probably means that the guest failed to find a route for the packet it wanted to send. What's in the guest's routing table? You need a route entry that says that 192.168.8.118 is reachable directly via the guest's eth0, and I don't see anything in your configuration that would create that route.

Yes, you should have eth0 as a separate interface, configured the same way you used to (before you started trying to set up VMs).

comment stop linux from emailing me cron errors?
Better to fix the script than to prevent cron from sending you the output. The next error might not be so trivial, and you don't want to miss it.

Note that newer Intel processors include a built-in hardware RNG, which should alleviate this problem.

comment Getting VMWare ESXi 5.0.0 with RAID using the Intel X79 chipset to work
If you do the software RAID within the VMs, you'd need to install the OS within its own software RAID array so that losing one disk won't take out the OS. Linux supports that; I don't know about Windows. If you're using Linux, make sure to install the bootloader (probably GRUB) onto each drive, since that lives outside the RAID array.

comment Getting VMWare ESXi 5.0.0 with RAID using the Intel X79 chipset to work
Your motherboard's specs say that it has an Intel X79 chipset, and Wikipedia says that the X79 has "Intel Rapid Storage Technology", which is the new name for what they used to call Matrix RAID. The 8086 in that PCI ID is Intel's vendor code.
