Here is the dmesg output within the guest. I am running KVM-39 on Ubuntu 2.6.20 kernel, 32 bit for both host and guest. [ 540.144000] Qumranet_hypercall_driver [ 540.148000] pci dev 0000:00:04.0 (id 5002:2258 rev 00) is a guest hypercall device [ 540.148000] PCI: Found IRQ 9 for device 0000:00:04.0 [ 540.148000] hypercall_init_board: PIO region size == 0x100 [ 540.148000] hypercall_init_board: MMIO region size == 0x00 [ 540.148000] name=: base_addr=0xc200, io_addr=0x1c200, IRQ=9 For what it's worth, I can compile the driver/hypercall.c file that comes with kvm-39. However, I can't compile your hypercall.c implementation, I get the following error: make -C /lib/modules/2.6.20-16-generic/build M=`pwd` "$@" make[1]: Entering directory `/usr/src/linux-headers-2.6.20-16-generic' CC [M] /home/kvm/kvm-userspace/drivers/hypercall.o /home/kvm/kvm-userspace/drivers/hypercall.c: In function ‘hypercall_do_tasklet’: /home/kvm/kvm-userspace/drivers/hypercall.c:226: error: invalid lvalue in unary ‘&’ /home/kvm/kvm-userspace/drivers/hypercall.c:226: error: invalid lvalue in unary ‘&’ /home/kvm/kvm-userspace/drivers/hypercall.c:231: warning: implicit declaration of function ‘hypercall_tx’ /home/kvm/kvm-userspace/drivers/hypercall.c: At top level: /home/kvm/kvm-userspace/drivers/hypercall.c:236: error: static declaration of ‘hypercall_tx’ follows non-static declaration /home/kvm/kvm-userspace/drivers/hypercall.c:231: error: previous implicit declaration of ‘hypercall_tx’ was here /home/kvm/kvm-userspace/drivers/hypercall.c: In function ‘hypercall_interrupt’: /home/kvm/kvm-userspace/drivers/hypercall.c:302: warning: passing argument 1 of ‘__constant_memcpy’ makes pointer from integer without a cast /home/kvm/kvm-userspace/drivers/hypercall.c:302: warning: passing argument 1 of ‘__memcpy’ makes pointer from integer without a cast /home/kvm/kvm-userspace/drivers/hypercall.c: In function ‘hypercall_open’: /home/kvm/kvm-userspace/drivers/hypercall.c:320: warning: passing argument 2 of ‘request_irq’ from incompatible pointer type /home/kvm/kvm-userspace/drivers/hypercall.c:326: warning: assignment makes integer from pointer without a cast /home/kvm/kvm-userspace/drivers/hypercall.c:328: error: ‘hypercall_task’ undeclared (first use in this function) /home/kvm/kvm-userspace/drivers/hypercall.c:328: error: (Each undeclared identifier is reported only once /home/kvm/kvm-userspace/drivers/hypercall.c:328: error: for each function it appears in.) make[2]: *** [/home/kvm/kvm-userspace/drivers/hypercall.o] Error 1 make[1]: *** [_module_/home/kvm/kvm-userspace/drivers] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.20-16-generic' make: *** [all] Error 2 Thanks, Cam ----------------------------------------------- A.
