Only a few hypercalls are allowed to be executed in an HVM guest. Console_io() is, in any case, only really for use by dom0. If you want to get debug output, you can send bytes to I/O port 0xe9. See tools/firmware/hvmloader/ directory for a printf() example. -- Keir On 26/9/07 13:37, "James Harper" <james.harper@xxxxxxxxxxxxxxxx> wrote: > When I do HYPERVISOR_console_io from windows > ('HYPERVISOR_console_io(CONSOLEIO_write, 12, "hello world!");'), 'xm > dmesg' says: > > " > (XEN) hvm.c:756:d78 HVM vcpu 78:0 bad hypercall 18. > " > > 78 is the DomID of my Windows DomU... so either I'm not passing the > parameters correctly, or console_io is not (any longer?) functional... > xen is 3.1.0. > > Any suggestions? > > Thanks > > James > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
