[Bug 471446] [NEW] qemu segfaults with a -cpu option

[Sergei Ivanov]

Public bug reported:

Binary package hint: qemu-kvm

When I run `qemu -cpu pentium' or `qemu -cpu 486' or similar, it segfaults immediately (a qemu window appears for a brief moment, then it dies). If I add -no-kvm to the command line, it starts normally.
The host system is x86_64, intel CPU with virtualization support.
