The following was what I did.
1) dd if=/dev/zero of =centos_raw.img bs=1024 count=8000000
2) install the os centos 5.5 x64 in the image file centos_raw.img and the correspongding config file is :
kernel = "/home/pvm/vmlinuz-2.6.18-194.el5xen"
ramdisk = "/home/pvm/initrd-2.6.18-194.el5xen.img" memory = 768 #maxmem = 768 name = "centos_raw_pv" vcpus = 1 vif = ['mac=00:24:7C:3C:CE:EF,bridge=eth0'] disk = ['tap:aio:/home/pvm/centos_raw.img,xvda,w'] root = "/dev/xvda1 ro"
3) qemu-img-xen create -b centos_raw.img -f qcow2 centos_raw_qcow2_1.img 5G
4) xm create centos_raw_qcow2_1.cfg and the centos_raw_qcow2_1.cfg is just like this:
kernel = "/home/pvm/vmlinuz-2.6.18-194.el5xen"
ramdisk = "/home/pvm/initrd-2.6.18-194.el5xen.img" memory = 768 name = "centos_raw_qcow2_1_pv" vcpus = 1 vif = ['mac=00:24:7C:3C:C1:EF,bridge=eth0'] disk = ['tap:qcow2:/home/pvm/centos_raw_qcow2_1.img,xvda,w'] root = "/dev/xvda1 ro"
however I'm failed.the error message after the above command is entered is :
Using config file "./centos_raw_qcow2_1.cfg".
Error: Device 51712 (tap) could not be connected.Setting up the backend failed. See the log files in /var/log/xen/ for details.
So I have tried another way.
after I install centos in centos_raw.img, I did the following:
qemu-img-xen convert -O qcow2 centos_raw.img centos_qcow2.img
here this image file centos_qcow2.img can be running normally with the config file :
kernel = "/home/pvm/vmlinuz-2.6.18-194.el5xen"
ramdisk = "/home/pvm/initrd-2.6.18-194.el5xen.img" memory = 768 name = "centos_raw_pv" vcpus = 1 vif = ['mac=00:24:7C:3C:CE:EF,bridge=eth0'] disk = ['tap:qcow2:/home/pvm/centos_qcow2.img,xvda,w'] root = "/dev/xvda1 ro"
Then I input the command below:
qemu-img-xen create -b centos_qcow2.img -f qcow2 centos_qcow2_qcow2.img 5G
and I edit the config file centos_qcow2_qcow2.cfg:
kernel = "/home/pvm/vmlinuz-2.6.18-194.el5xen"
ramdisk = "/home/pvm/initrd-2.6.18-194.el5xen.img" memory = 768 name = "centos_qcow2_qcow2_pv" vcpus = 1 vif = ['mac=00:24:7C:3C:CE:1F,bridge=eth0'] boot="c" disk = ['tap:qcow2:/home/pvm/centos_qcow2_qcow2.img,sda,w'] root = "/dev/sda1 ro"
and implement the command:
xm create centos_qcow2_qcow2.cfg
but what was posted were:
Using config file "./centos_qcow2_qcow2.cfg".
Error: Device 2048 (tap) could not be connected.Setting up the backend failed. See the log files in /var/log/xen/ for details.
I need to run a para-virtualized machine whose image file is qcow2 format and is based on another image file.What can i do with this?I need your help. In fact,I have no way to go through.My boss just now tell me that if I could not overcome this problem ,the only thing I could do is to die.HELP! ANY suggestion would be fine! _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxx http://lists.xen.org/xen-users
