Hey, all! I am new to KVM and IVSHMEM. I am trying to create a virtual machine which would use IVSHMEM to communicate with other VM's when they are located on the same host machine. For this, I am trying the instructions given in this blog: http://www.abhijeet-dev.net/content/ivshmem-qemu-kvm-interrupts. However, when I try to create a VM using the following command: kvm -boot d -hda ~/Fedora-Live-Desktop-x86_64-19-1.iso -cpu core2duo -m 1G chardev socket,path=/tmp/nahanni,id=nahanni2 -device ivshmem,chardev=nahanni,size=512m,ioeventfd=on,vectors=8,index=2 I get the following error: kvm: -m 1G: drive with bus=0, unit=0 (index=0) exists I would like you to know that I had already created a VM using the same command, but a different image kvm -boot d -hda lupu-528.005.iso -cpu core2duo -m 1G chardev socket,path=/tmp/nahanni,id=nahanni2 -device ivshmem,chardev=nahanni,size=512m,ioeventfd=on,vectors=8,index=2 Please let me know how to resolve this error. Also, it would be nice if someone could give me some good tutorials on using IVSHMEM or other inter-VM communication mechanisms. -- Thanks and regards, Jobin Raju George Final Year, Information Technology College of Engineering Pune Alternate e-mail: georgejr10.it@xxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
