[Xen-users] Fwd: VM''s vif didn''t work in Xen 4.2 unstable
This message should be sent to the list (sorry if it was already). ---------- Forwarded message ---------- From: Tiantian Liu <tiantianl@gmail.com> Date: Fri, Jul 29, 2011 at 9:37 AM Subject: VM''s vif didn''t work in Xen 4.2 unstable To: todd.deshane@xen.org Hi I built Xen-4.2-unstable and kernel-2.6.32.40 on CentOS 5.5 successfully! I also implemented fault tolerance and high avaliability via remus. But I got new problems: 1. The vif of VM didn''t work, when I start a new VM by command: "xm cr myvm.hvm", system returned message: "the <VM> does not exist". my VM''s configuration file is: ernel = "hvmloader" builder=''hvm'' memory = 512 name = "myvm" vcpus=4 vif = [ ''type=ioemu, bridge=eth0,mac=00:16:3e:3a:7a:dd'' ] pae = 1 acpi = 1 apic = 1 #disk = [ ''file:/home/xen/tpl/hvm/base.img,hda,w'', ''file:/home/xen/tpl/hvm/CentOS-5.5-x86_64-bin-DVD-1of2.iso,hdc:cdrom,r'' ] disk = [ ''file:/home/xen/tpl/hvm/win.img,hda,w'', ''file:/home/xen/tpl/hvm/windows-XP.iso,hdc:cdrom,r'' ] device_model = ''qemu-dm'' boot="cd" sdl = 0 vnc = 1 vnclisten = "0.0.0.0" stdvga = 0 serial = "pty" if I deleted the "vif = [ ''type=ioemu, bridge=eth0,mac=00:16:3e:3a:7a:dd'' ]" , the vm started successfully, but the VM could not access network. I have installed the bridge-utilty package properly. I checked the /val/log/message, it showed: Jul 29 04:04:34vnix06 kernel: [ 205.540203] device vif1.0 entered promiscuous mode Jul 29 04:04:34 vnix06 kernel: [ 205.545969] eth0: port 2(vif1.0) entering forwarding state Jul 29 04:04:34 vnix06 kernel: [ 205.811565] eth0: port 2(vif1.0) entering disabled state Jul 29 04:04:34 vnix06 kernel: [ 205.818948] device vif1.0 left promiscuous mode Jul 29 04:04:34 vnix06 kernel: [ 205.818955] eth0: port 2(vif1.0) entering disabled state Jul 29 04:04:35 vnix06 logger: /etc/xen/scripts/block: Path closed or removed during hotplug add: backend/vbd/1/5632 state: 6 Jul 29 04:04:35 vnix06 logger: /etc/xen/scripts/block: xenstore-read backend/vbd/1/5632/node failed. Jul 29 04:04:35 vnix06 logger: /etc/xen/scripts/block: /etc/xen/scripts/block failed; error detected. could you tell me how to address this problem? 2. The NFS worked well in CentOS5.5, but when I compiled kernel-2.6.32-40 and Xen-4.2-unstable and got into dom0. the NFS didn''t work, and could not mount the remote NFS server. I tried command: "service nfs restart", but the failed. I used command: "mount <IP>:/home /mnt", the system returned: mount <IP>/home /mnt mount.nfs: No such device what''s wrong? I am waiting for your help! thank you very much! -- Todd Deshane http://www.linkedin.com/in/deshantm http://www.xen.org/products/cloudxen.html http://runningxen.com/ _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
