Windows 7 Guest on MacOS & Win7 hosts from USB stick

Post by GAP »

Hello,

I have my win7 guest running on mac host and everything is fine with this.
Also I have a laptop running win7 and I installed VB on it too.
What I need to do is to run same win7 guest on my mac os and my win7 hosts using my USB flash drive. Was trying to copy the .vdi & .vbox files into tmy usb stick but when I plugged it into my win7 host it was trying to load for 1 hour after it finally loaded but was very slow and didnt want to move.

Please advice how I can use same win7 guest on 2 different hosts like mac and win.

Transferring/copying/moving/sharing a VM between two hosts should work with the following caveat: shared folders. Other than that, the closer the specs of the hosts, the better. Now, if it works on one and crawls on the other, that means that the two hosts do not have similar RAM, # CPUs, and CPU capabilities. You've got to use the least common denominator.

Do the following for both hosts (obviously one on each):
Start the VM. Shut it down once it boots completely (not paused or saved). Right-click on the VirtualBox Manager and select "Show Log". Save the "VBox.log" (just the first one), ZIP it and attach it in your response (see the "Upload attachment" tab below the reply form).

Moving to "Using VirtualBox" from "OSX Hosts" since this involves more than a specific host.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

I think there you have it. USB sticks are not for running regular operating systems, they're for transferring files. You can run a Live-CD-style OS off a USB stick, but that kind of OS loads a ram drive to do its normal operations and does not write back to the USB stick much if at all. A regular OS does a lot of writing, which is hard on and slow on a USB stick.

Try copying the guest to the Win7 host's hard drive then running it there. You may get better performance. Be sure the host OS has had several minutes to boot up and stabilize before trying to run the guest.

Once you get the guest on a normal platter or solid-state drive not attached via USB, then if you have slowness issues, the logs Mpack was looking for will clue us in.
