KVM only virtualizes a CPU that matches the host. If you're on a 64-bit host, then it only virtualizes a 64-bit CPU. It doesn't virtualize a 32-bit CPU - if you want a true 32-bit cpu on a 64-bit host you need to emulate with QEMU instead. That said its rather pointless because you can run a 32-bit guest OS in a 64-kvm KVM vm just fine. > - after select i386 creating the disk image virt-manager crash with some > python backtrace as can't connect the guest.

There's many things which can go wrong - some versions of KVM have broken PXE support. Start off by tracing the network traffic in the host using tcpdump. It may also be an incompatability with your DHCP server and etherboot Dan -- |: Red Hat, Engineering, Boston -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| _______________________________________________ et-mgmt-tools mailing list et-mgmt-tools@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/et-mgmt-tools
