Hi, I would like to start my vm with the forddtest1.hvm, in which my disk line is disk = [ ''tap2:tapdisk:qcow2:/home/vm/hvm/forddtest1.qcow2,xvda,w''] However,both the xl and xm commands could not use the file "forddtest1.hvm" to start a vm successfully.The following is my specific situation. [root@localhost hvm]# xm create forddtest1.hvm Using config file "./forddtest1.hvm". Error: (''create'', ''-aqcow2:/home/vm/hvm/forddtest1.qcow2'') failed (55808 blktap kernel module not installed ) [root@localhost hvm]# xl create forddtest1.hvm Parsing config file forddtest1.hvm Unknown tapdisk type: tapdisk If I configure the vm''s disk like this: disk = [ ''tap2:qcow2:/home/vm/hvm/forddtest1.qcow2,xvda,w''] everthing will be OK. What''s wrong with it?Who could help me solve this problem? A Newbie _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
