Hi everyone @parallels forum, Here's a question for you to see if I am doing something wrong or... My config is : MacPro 2 X2.93Ghz Xeon ; 40GB RAM ; MacOsX 10.10.2 Yosemite ; Latest version of parallels running Linux Mint Cinnamon 17.1 ; RAID Card with 2 X 2TB RAID0 and 2X3TB RAID0 + 1 boot SSD. I installed Linux Mint and settings are "mapped mac volumes" and "shared home folder". The folders appear on the desktop all right... But I installed this VM basically to be able to build my own custom ROM using Linux. As you might know, doing so eats up a lot of disk space and uses a lot of computing resources. So what I wanted to do is keep the Virtual HD on my SSD but keep it rather small (120Gb) and then download the ROM sources to one of the external mapped volumes. Did everything... but the downloading (called "repo sync") always fails with a Linux VM freeze. I found the culprit : it's memory. I allocated 32GB of RAM to the Guest OS. Weird enough, each time I download to an external hard drive, the whole sources are stored in RAM and thus, after a while, memory is saturated. So machine freeze. This does not happen if I download to the virtual hard drive. Is this normal ? I don't think so... but is anyone aware of this ? And is there a workaround ? Thanks a lot for your answers. Regards.
