Change Penryn to max

[sickcodes]

As stated in QEMU 6

Can test currently with:

-e CPU=max \

[user@hostname ~]$ qemu-system-x86_64 -cpu help
x86 Penryn                (alias configured by machine type)                        
x86 Penryn-v1             Intel Core 2 Duo P9xxx (Penryn Class Core 2)              
...
x86 base                  base CPU model type with no features enabled              
x86 host                  KVM processor with all supported host features            
x86 max                   Enables all features supported by the accelerator in the current host

    -cpu max,vendor=GenuineIntel \
    -machine q35,${KVM-"accel=kvm:tcg"} \

I am considering the following changes.

VMX doesn't show up, but apparently it should work on Intel.

I will give it a test on Digital Ocean, which lets you select AMD or Intel, unless someone wants to.

Hey sickcodes. Is there a reason why this isn't merged?

Hey sickcodes. Is there a reason why this isn't merged?

Haven't had much time to be able to test all the images with the maxed out CPU. I'll give it a shot today

This isn't 100% required, however if the following provides a performance boost, I'll merge it:

-e CPU=max \
-e CPUID_FLAGS='vendor=GenuineIntel' \
