[QNX hypervisor 2.2 user manual]6.3.2 configuring VM

Like other virtual devices , We can add shmem Virtual device to VM Configuration in progress .

If you want to shmem Virtual devices are included in the hosting that will use shared memory Services Host Of VM in , You need to add this virtual device to qvm Configuration in progress . Need to be in qvm Configuration in progress , Make sure to serve all who use shared memory Guest Of VM Add pair shmem Configuration of virtual devices . as follows ：

# qnxcluster.qvmconf example
#Give this guest a name
system cluster
ram 1024M
cpu
cpu
load /emmc/QNX_cluster.ifs
vdev ioapic
        loc 0xf8000000
        intr apic
        name myioapic
vdev ser8250
        intr myioapic:4
vdev timer8254
        intr myioapic:0
vdev mc146818
vdev shmem
vdev pckeyboard

Above ,shmem Configuration lines related to virtual devices , as follows ：

vdev shmem

This is a PCI equipment . If you specify its loc and intr attribute , It will serve as a MMIO The equipment is in the specified position Guest so , as follows ：

vdev shmem
	create TEST1,0xf0000	# name is TEST1 with size of 0xf0000
	loc 0x10000000		# location of factory page
	intr myioapic:10	# hardware interrupt used for signaling

Based on the above configuration ,qmv The process will create a named “TEST1” The share of
