Re: [Qemu-discuss] qemu -cpu host

Kernel should be OK (it is a distribution kernel), fixes are backported, but qemu version is very old. On Mon, 6 Feb 2017 13:06:16 +0100 Vincenzo Romano wrote: > Yes, both the kernel (for the KVM) and Qemu are quite behind... > > -- > Vincenzo Romano -

How did you get that translation from "qemu -cpu host" to "...-cpu SandyBridge,+vme,+ds,+acpi,+ss,..." ? El 06/02/17 a les 12:15, akhilesh rawat ha escrit: > thanks , but if you see the guest which was run as > > > qemu -cpu host > > > has auto generated model as SandyBridge in KVM

Which version of qemu are you using? Which version of the kernel are you running? -- Vincenzo Romano - NotOrAnd.IT Information Technologies -- NON QVIETIS MARIBVS NAVTA PERITVS 2017-02-06 12:19 GMT+01:00 akhilesh rawat : > [root@centos qemu]# /usr/libexec/qemu-kvm

thanks , but if you see the guest which was run as qemu -cpu host has auto generated model as SandyBridge in KVM process. usr/libexec/qemu-kvm -name compute-0 -S -machine pc-i440fx-rhel7.0.0,accel=kvm,usb=off -cpu

[Qemu-discuss] Qemu "-cpu host" option

Hi, What does Qemu do when invoked using "-cpu host" option that sets target CPU same as the host CPU? Is it that when this option is used Qemu performs no binary translation? Because the target CPU is same as host CPU, code compiled for target CPU may run directly on host CPU. Or does Qemu

Re: [Qemu-discuss] Qemu "-cpu host" option

Sorry, I should have mentioned this earlier. I'm running it on x86_64 architecture, and I'm using -enable-kvm . So in this case, does Qemu binary translate even when "-cpu host" is used? Thanks, Abhinav On Thu, Nov 26, 2015 at 11:11 PM, Peter Maydell wrote: > On 26
