Hi,
I am using Ubuntu 16.04 on 64 Bit, i7 machine and following CAmkES x86
VM instructions available at:
https://docs.sel4.systems/CAmkESVM
I am able to successfully run single guest vm. I am now trying to run 2
guest vms at the same time. For this, I changed
a) minimal.camkes as follows:
--------------------------------------------------------------------------------------------------------------------------------
#ifdef HAVE_AUTOCONF
#include <autoconf.h>
#endif
import <VM/vm.camkes>;
#include <configurations/vm.h>
#define VM_GUEST_CMDLINE "earlyprintk=ttyS0,115200 console=ttyS0,115200
i8042.nokbd=y i8042.nomux=y \
i8042.noaux=y io_delay=udelay noisapnp pci=nomsi debug root=/dev/mem"
component Init0 {
VM_INIT_DEF()
}
component Init1 {
VM_INIT_DEF()
}
assembly {
composition {
VM_COMPOSITION_DEF()
VM_PER_VM_COMP_DEF(0)
VM_PER_VM_COMP_DEF(1)
}
configuration {
VM_CONFIGURATION_DEF()
VM_PER_VM_CONFIG_DEF(0)
VM_PER_VM_CONFIG_DEF(1)
vm0.simple_untyped23_pool = 20;
vm0.heap_size = 0x2000000;
vm0.guest_ram_mb = 128;
vm0.kernel_cmdline = VM_GUEST_CMDLINE;
vm0.kernel_image = "bzimage";
vm0.kernel_relocs = "bzimage";
vm0.initrd_image = "rootfs.cpio";
vm0.iospace_domain = 0x0f;
vm1.simple_untyped23_pool = 20;
vm1.heap_size = 0x2000000;
vm1.guest_ram_mb = 128;
vm1.kernel_cmdline = VM_GUEST_CMDLINE;
vm1.kernel_image = "bzimage";
vm1.kernel_relocs = "bzimage";
vm1.initrd_image = "rootfs.cpio";
vm1.iospace_domain = 0x0f;
}
}
---------------------------------------------------------------------------------------------------------------------------------
b) CMakeLists.txt as follows:
---------------------------------------------------------------------------------------------------------------------------------
cmake_minimum_required(VERSION 3.8.2)
project(minimal)
# Include CAmkES VM helper functions
include("../../vm/camkes_vm_helpers.cmake")
include("../../vm-linux/vm-linux-helpers.cmake")
# Declare VM component: Init0
DeclareCAmkESVM(Init0)
DeclareCAmkESVM(Init1)
# Get Default Linux VM files
GetDefaultLinuxKernelFile(kernel_file)
GetDefaultLinuxRootfsFile(rootfs_file)
# Decompress Linux Kernel image and add to file server
DecompressLinuxKernel(extract_linux_kernel decompressed_kernel
${kernel_file})
AddToFileServer("bzimage" ${decompressed_kernel} DEPENDS
extract_linux_kernel)
# Add rootfs images into file server
AddToFileServer("rootfs.cpio" ${rootfs_file})
# Initialise CAmkES Root Server with addition CPP includes
DeclareCAmkESVMRootServer(minimal.camkes)
---------------------------------------------------------------------------------------------------------------------------------
I can successfully build the system and 2 vm images are being created
namely:
vm0_group.bin, vm1_group.bin
On running the system using:
sudo ./simulate --machine q35,accel=kvm,kernel-irqchip=true --mem-size
2G --extra-cpu-opts "+vmx" --extra-qemu-args="-enable-kvm -net
nic,model=e1000 -net tap,script=no,ifname=tap0"
I get the following error:
---------------------------------------------------------------------------------------------------------------------------------
<<seL4(CPU 0) [decodeUntypedInvocation/209 T0xffbfec00 "rootserver"
@804853d]: Untyped Retype: Insufficient memory (1 * 4194304 bytes
needed, 2048 bytes available).>>
<<seL4(CPU 0) [decodeInvocation/542 T0xffbfec00 "rootserver" @804853d]:

[email protected]:767 [Err seL4_InvalidCapability]:
Untyped retype failed with unexpected error
seL4 root server abort()ed
Debug halt syscall from user thread 0xffbfec00 "rootserver"

Kernel entry via Unknown syscall, word: 523QEMU: Terminated
---------------------------------------------------------------------------------------------------------------------------------
I have 2 doubts:
a) Can someone suggest a possible way to get this running.
b) Is it possible to see the 2 VMs running on separate terminals at the
same time.
