Need #1: HDs take about $5/year to run. I don't think any virtualization has APM passthrough for drives.
Need #2: Every virtualization technology does this. ESX, Hyper-V, Xen, KVM, QEmu...
Want #1: With only two machines, which presumably will be running constantly anyway, how much bother are non-GUI tools?

ESXi (and I'm assuming that's what you're using, based on the mentioned "3i") doesn't include the GRUB menu.
According to VMWare's "Changing a forgotten root password on an ESX host" page:
Note: This article does not pertain to ESXi. Reinstalling is the only way to reset a root password on ESXi.
Perhaps the info found at "How to reset the root ...

You can't - oddly enough this professional grade software is not geared towards your decidedly home-based usage requirement - therefore it does not have any form of code built in to detect a button press and trigger a shutdown.
Why not try a consumer product such as VMWare's Workstation which is much more likely to be scriptable in this manner.

Absolutely!
However, this depends on the machine.
If it contains heat sensors in a standard industry accepted form, it is more than likely ESX/Vsphere can access them, along with fan information (see picture below).
Simple log on to vSphere client and click on the server, go to configuration > Health Status, and you should find the information there.

Yes, using vsphere client you can choose File->Export->Export OVF Template fill in the form and export the files to a local filesystem. This exported appliance should then load into your other virtualisation tools without any really issues. I've done this with CentOS6 (exported) and loaded it into VirtualBox.

It really will depend on the kind of VMs you will be running. Are the applications write heavy or read heavy?
Read heavy systems will be ok on a RAID-5, while RAID-10 (1+0) will be much faster on writes. The parity calculation with raid 5 takes a beating to RAID-5.
RAID-10 also has the disadvantage of using half of your storage for redundancy.
RAID-5 ...

A reachability of zero suggests that the VMs cannot communicate with one another - either because of basic network issues or due to firewall settings.
I would carry out a range of tests using
ping from NTP client to NTP server (but Ping is sometimes blocked by FW)
ssh from NTP client to NTP server (arguably less often blocked)
ntpdate -d 129.177.90.75

The Auto Start bug (VMware Community) introduced with 5.0 Update 1, which broke the VM Auto Start feature on the free version of ESXi. VMware released the ESXi patch "ESXi500-201207001" on July 12, 2012 which includes the fix.
You can download the patch from here: Download
You can review the bulletins and image profiles included with the patch from here:

If you have installed VMware ESXi server, you can manage the ESXi server using vSphere client. vSphere client works only on Windows host. If you don’t have vSphere client installed, download it from your local VMware Server home page. i.e go to http://{your-vmware-server-ip} to download ...

We have a couple of HP Microservers that boot Alpine Linux off USB sticks and having tried DD to make copies (took ages - gave up), I settled for CloneZilla (on a Parted Magic live CD) as it was quicker and also gave me backup files I could burn onto a CD and put in a fire safe as an added precaution.
You have to first do a partition backup of the USB stick ...

It depends on the OS you're making the backup with. If you can find a windows box, usbimagewriter for windows has worked pretty well in most cases, its a one click application to copy an image of a USB, and pop it back into the USB.

I just created 27 clones (2 complete IBM BladeCenters) of ESXi 4.1 using this tool.
It took the time it would have taken to manually install 2 or 3 Blades...
The Tool allows you to restore the same image on several usb-sticks simultaneously.

I have strong doubts about whether this would work. ESXi does support USB hardware passthrough, but not for every type of USB device.
Our system coped fine with USB memory sticks and a USB lead to a UPS for monitoring it, but ESXi would not 'see' the card/fob reader for our building security system so we could not pass it to a VM.
Probably best to ...

One step I would take is to see if the packets are getting to your guest at all. On your linux host, run
tcpdump -i eth0 tcp dst port 80
substituting "eth0" for whatever your interface is called. With that running, try and access your page (I would suggest using an "outside of your network" host like a cellphone using the carriers internet and not your ...

It is not possible to do this for ESXi. NFS access requires the use of the root user (UID 0) to access NFS shares and you have to disable root_squash.
For ESX there is "experimental support" for delegating NFS access to a separate account, as per this VMware document. That's VMware code for saying the functionality is there but if you run it on production ...

ESXi is a virtualization server. It virtualizes the VGA hardware also. You can't really use the native VGA. PCI pass-though might be an option, but I don't think it works for VGA. There is no 3D acceleration either, not useful for gaming.
It sounds like you would benefit most from the VMware Workstation product. For that you run a native host (either ...

Some people have had limited success using DirectPath I/O Passthrough with graphics cards in ESXi, of course your motherboard has to support it and not all graphics cards work so YMMV.
For things like gaming and media though, this'd not be a particularly great idea.

It seems that you need to get a live snapshot. There are a few solutions that will work:
Drive Snapshot - will backup your entire hard drive, even while you're using it
http://www.drivesnapshot.de/
XXCopy - will copy open files (I believe it uses the same snapshot technology)

I've used Drive Snapshot to ...

How do you have access to the vmdk/vmx files? How are you accessing your VM?
Are you in communication with an admin who does have ESXi console / VSphere Client access?
Snapshots of a running machine solves your problem:
First backup windows.vmx (so it doesn't reference the snapshot)
Get the administrator to snapshot the VM
Copy the windows.vmdk and ...

You don't want to run NTP or NTPDATE on a virtual machine. It should get its time from the system clock.
Check the UTC value in /etc/default/rcS. Try setting it from no to yes or vice-versa.
While you are at it add an exit 0 line to /etc/default/ntp. Alternatively set the NTPOPTION value to "-q". This will disable NTP on the virtual server.

These "proxy" applications are created by VMware Fusion and are located inside the .vmwarevm virtual machine bundle. Right-click your virtual machine, select Show Package Contents and open the Applications folder.
Does that folder exist? Does it contain applications? Does it contain the application you want the files to open with? Make sure in the virtual ...

According to the VMWare Forums, the correct way to fix this is to install:
sudo apt-get install libssl-dev perl-doc liburi-perl libxml-libxml-perl libcrypt-ssleay-perl ia32-libs
(Note, this is a big job, it downloads ~80Mb of stuff, and takes ~260Mb of disk space)

No you do not need those files. They are partition meta-data.
Each resource type is managed by one of 4 system files which are
created during the file system bootstrap process:
fbb.sf - file block bitmap.system file
pbc.sf - pointer block cluster.system file
sbc.sf - sub-block cluster.system file
fdc.sf - file descriptor cluster.system file

Depending on your version (see comments) there might be downtime for adding a second disk. Older ESXi versions can't add the disk while the VM is running.
Without LVM you also need to boot into recovery/emergency mode with your installation disc, since you can't extend the active system partition while it's mounted.
There are examples around on the web on ...

You need more memory for your virtual machine guest os, ESXi requires at least 2GB memory.
See Requirements:
CPU
Minimum: Single socket, dual core
Ideal: Dual-socket, 4 or more cores per CPU
Memory
Minimum: 2GB
Ideal: 8+GB
Network
Minimum: one NIC, plus one for Management interface
Ideal: One for Management Interface plus multiple ...

It would certainly be better to either use Hyper-V or ESXi, but not one on top of the other. It would slow down the system, and on top of that is not necessary. Which one to use out of Hyper-V and ESXi on the other hand is a completely different question and depends on what you will be using the virtual servers for.

In ESXi, create a virtual switch, not connected to the outside world and one that is connected to the outside world. On the MikroTik Router, give it 2 network connections, one to the internal and one to the external connections. All your Windows boxes should just connect to the internal. In the Mikrotik router, tell it to give IPs (DHCP server) to the ...
