But how many slots we can use,the number is limited by the host kernel?Do any one has the same problem? Can you please provide the complete QEMU command line when reporting QEMU bugs? Just dumping a log of Nova is not very useful for debugging QEMU problems. Thanks. [Expired for QEMU because there has been no activity for 60 days.]
