Subject: [Bug 43501] all 32bit binaries produce "Illegal Instruction" after KVM migration from AMD -> Intel host

Try the following command line (on both hosts)
qemu -cpu phenom,vendor=AuthenticAMD
Note that 32-on-64 applications will suffer a performance penalty when using
cross-vendor migrations. You can mitigate this by using vdso32=0 on the guest
kernel command line (but this is slower than the default, when not doing
cross-vendor migration).
