This page documents current status, known issues and work in progress. Some of these may impact your development or hypervisor usage.
The Resource Manager being the root-VM, manages creation of the Primary VM (HLOS) and controls the rights to create additional VMs. In the Gunyah Resource Manager design, VM management services are provided by the Resource Manager
Gunyah patches are required in Linux and the CrosVM VMM to support SVM loading.
- Only QEMU serial communication is tested. Using host Linux networking (qemu virtio) with adb (network) connection will permit greater flexibility in connecting to the device.
- SVM booting with Crosvm uses uart emulation, its very slow.
- Crosvm opens the UART console in the current terminal, so it is via the host uart terminal. We have not configured a way to open multiple terminals yet.
- Debugging a system running QEMU with a remote gdb connection is unstable.
- Launching of multiple SVM's simultaneously from PVM, because of the known issue of having only one console available.
- Hardcoded platform parameters
- Memory address ranges are hardcoded (get from dtb nodes)
- Dtb address is hardcoded (get from register)
