This happens because x86_cpu_get_migratable_flags() does not support CPUID_EXT2_AMD_ALIASES. After cherry-picking upstream patch 9997cf7bdac056aeed246613639675c5a9f8fdc2, that moves CPUID_EXT2_AMD_ALIASES code to after x86_cpu_filter_features(), the problem is fixed. Other QEMU versions are properly fixed and don't face this issue.
Cherry-picking commit and re-building the package makes it to work:

[Impact]
* QEMU does not work in some AMD hardware when using host-passthrough as cpu-mode (usually to allow nested KVM to work).
[Test Case]
* to use Xenial qemu (1:2.5+dfsg-5ubuntu10.36 ou 1:2.5+dfsg-5ubuntu10.37)
* to use the following XML file: https://paste.ubuntu.com/p/BSyFY7ksR5/
* to have AMD FX(tm)-8350 Eight-Core Processor CPU or similar
[Regression Potential]
* initial qemu code could be affected, disallowing other guests, in other architectures, to be started
* suggested patch is simple, being a positional change only
