It would be great to image a stick from a virtual pc. ¿It's possible? Thanks,Juan

Yes, that's how I build it and work on new versions now. All you need to do is a CD Boot in VirtualBox using the iso file from http://wiki.ubermix.org/page/CD_Install (http://wiki.ubermix.org/page/CD_Install). Insert the USB key you want to use and capture it in the virtual machine, then all typical options will be available to you.

Jim, I've been trying to load Ubermix through a USB key into virtual box to start building my image, however everytime I go to image my virtual machine after booting from a cd/iso I get a bunch of "Unable to open /dev read-write" errors, then no imaging occurs. I've tried different types of virtual disks and ensured I have read-write permissions to the directory. What am I missing?

Anyone have any suggestions on getting Ubermix 2.0 to load into virtual box?

Sounds like your disk is too small in your virtual machine. Default install wants 8Gb for the base, 4Gb for the user changes, and at least 2Gb for home folders. You could squeeze that down to about 10Gb when installing by choosing 2. Advanced Install and entering the minimum sizes for the partitions.

You would be correct. Thanks for the guidance!

Now for the next problem. After building my base image and booting to the CD and capturing on my thumbdrive, I am not able to boot a machine that I imaged with that drive. It's my base Aspire v5-131. The image I worked with was the 64-bit Ubermix 2.0. No errors were present during imaging, although it did go super fast. Not really sure what the problem is actually since everything appears to work great.

Hey Jim (or others), any advice on this?

Could be that vbox didn't finish writing to the key. Definitely watch the usb indicator at the bottom of the vbox window to make sure that it is done before rebooting. Usually takes an extra 30 seconds or so.

Just noticed this...While capturing the image in VB I received an error saying "split: /root/base_image.gz.aa: No space left on device. It's a 4Gb thumb drive...Also received error on an 8Gb freshly imaged with the 2.02 base...

You'll need to use gparted to make the partition bigger on the key. The default key partition is only 2.3 Gb. See http://ubermix.org/customization.html (http://ubermix.org/customization.html) for details.

Thanks, that seems to have fixed it. Now just to get auto-updates working...
