Dear Qemu technical experts:
My question is whether QEMU also needs to support specific CPU models when KVM is turned on? Here is the description of the problem I encountered.
I want to run KVM+QEMU on my mobile phone, which is piexl7. Compiled the corresponding qemu-system-aarch64 bin.
Then put it into the mobile phone to run, and found that qemu would hang, and then stopped running. The command line is as follows
./qemu-system-aarch64 -enable-kvm -m 1024 -M virt -cpu host \
-nographic -kernel Image -drive if=none,file=disk_oe64.img,id=fs -device virtio-blk-device,drive=fs \
-append "earlyprintk console=ttyAMA0 mem=512M rootwait root=/dev/vda rw"
If I don't use KVM, it can run completely using QEMU to realize virtual hardware. The command is as follows:
./qemu-system-aarch64 -m 512 -M virt -cpu cortex-a57 -nographic -kernel Image \
-drive if=none,file=disk_oe64.img,id=fs -device virtio-blk-device,drive=fs \
-append "earlyprintk console=ttyAMA0 mem=512M rootwait root=/dev/vda rw"
Best Regards,
