Hi everyone,
I incidentally configured two IDE controller for my machine-1.2 VM(it
might be virsh attach-disk to blame), and I got the error message
"Only a single IDE controller is unsupported...". I can't understand
this error message, I think it means I HAVE to configure two or more
IDE controllers until I looked it up in the source.
At libvirt-1.2.22/src/qemu/qemu_command.c:
4916 case VIR_DOMAIN_CONTROLLER_TYPE_IDE:
4917 /* Since we currently only support the integrated IDE controller
4918 * on 440fx, if we ever get to here, it's because some other
4919 * machinetype had an IDE controller specified, or a 440fx had
4920 * multiple ide controllers.
4921 */
4922 if (qemuDomainMachineIsI440FX(domainDef))
4923 virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s",
4924 _("Only a single IDE controller is
unsupported "
4925 "for this machine type"));
I didn't dig VIR_DOMAIN_CONTROLLER_TYPE_IDE up, but reasoning from the
comment, I think this error message should be something like "More
than one IDE controllers is not supported for this machine type"
