Hi, I'm having a slight problem with some user space code that I have written which causes an error. When I attempt to map more than 67 pages of host memory into the guest, KVM_CREATE_VCPU fails. Please see the link below for a small test that I have written which causes the problem. https://pastebin.com/qjZJ5MMN Note that I am using an Intel Core i7 7500U CPU. My kernel version is 4.10.0-40 (x64). I would appreciate any help or advice that you can offer. Kind Regards, Darren Anderson
