I don't understand what could eats the RAM of the host because i have 32GB Memory RAM. I have 16GB for the Host and 16GB (with Hugepages) for the Guest. My Windows_10.img is in an Ext2 partition.
I try actually to use the IGD (Intel graphic card) to the Host and the GTX970 to the Guest and i have no problems. How is it possible to have conflict between both Nvidia card. I have only two solutions : 1- Use both Nvidia cards but only 2GB Memory RAM in virt-manager and i don't know if with 10GB of Memory swap in Win10 is enough to play at AAA games 2- Use IGD for Linux and the Nvidia for the Host. 2016-10-08 14:36 GMT+02:00 Bronek Kozicki <b...@spamcop.net>: > Perhaps you have something eating into RAM of the host.
