For simplifying let’s pick up the comparison of 2 virtual machines : each one is well parametrized so they none of them can fill the ram, even if they are alone (ex :max use 4Gb of ʀᴀᴍ and 64Gb available on the host). Does the first virtual machine can read the ʀᴀᴍ of the second ? No ! Does the second virtual machine can read the ʀᴀᴍ of the first ? Neither ! In both case they share the same memory hardware. The same apply to ɢᴘᴜs with ᴄᴘᴜs on ᴀᴘᴜs but with the hypervisor ᴏꜱ being replaced by a pure hardware one, so there’s no software parts (with the exception of the memory allocated memory ratio being controllable in the ʙɪᴏꜱ or the ᴜᴇꜰɪ firmware) -- You are receiving this mail because: You are the QA Contact for the bug.
