Subject: [gentoo-user] Recommendation for CPU type in QEMU?
Date: Wed, 31 Jul 2013 10:11:39
1 I'm looking at setting up 32-bit WINE to run a 32-bit Windows app.
2 Since I'm on a pure 64-bit (no multi-lib) machine, that doesn't exactly
3 work, which is why I'm looking at QEMU. I need to run WINE in 32 bit
4 mode, on a 32-bit install in a VM. Is a 64-bit virtual cpu type
5 recommended anyways? Are the "qemu" and "kvm" cpu types faster/slower?
6 And what would they be listed as in the kernel .config?
8 I'm not familiar with all the weird codenames for Intel's chips.
9 What's the hierarchy between Nehalem/Westmere/SandyBridge/Haswell ?
10 Here's the list of available types...
