Hi,<br><br>Yes I'm running oned as root and I already used the "no root squash" option. Why root would create issues ?<br><br><br><br>> Date: Wed, 1 Jun 2011 17:55:33 +0200<br>> Subject: Re: [one-users] Cannot start VM with XEN<br>> From: jfontan@gmail.com<br>> To: sokar6012@hotmail.com<br>> CC: users@lists.opennebula.org<br>> <br>> Are you running oned as root? If you are doing so take into account<br>> that nfs can give you some problems with nfs mounts and root<br>> ownership. Maybe you can solve those problems adding no_root_squash to<br>> export/mount options.<br>> <br>> Anyway, the recommended way to run opennebula is with its own user and<br>> having that same user/id in all the nodes.<br>> <br>> On Fri, May 27, 2011 at 3:18 PM, anthony garnier <sokar6012@hotmail.com> wrote:<br>> > Hi,<br>> ><br>> > I've just installed openebula and I can't create a VM.<br>> > I use Xen hypervisor 3.1.2<br>> ><br>> > Frontend : one<br>> > CentOS 5.5 64bits<br>> ><br>> > Node in cluster : node01<br>> > CentOS 5.5 64bits for Dom0<br>> > Debian lenny i386 for DomU<br>> ><br>> > I can directly create a fully running Debian VM with xm cmd but when I use<br>> > # onevm create debian.one<br>> ><br>> > # onevm list<br>> > ID USER NAME STAT CPU MEM HOSTNAME TIME<br>> > 17 root debian fail 0 0K<br>> > node01 00 00:01:04<br>> ><br>> ><br>> > content of debian.one :<br>> ><br>> > NAME = debian<br>> > CPU = 1<br>> > MEMORY = 512<br>> ><br>> > OS = [<br>> > kernel = "/boot/vmlinuz-2.6.26-2-686-bigmem",<br>> > initrd = "/boot/initrd.img-2.6.26-2-686-bigmem",<br>> > root = "xvda1" ]<br>> > #OS = [BOOTLOADER = /usr/bin/pygrub]<br>> ><br>> > DISK = [<br>> > source = "/opt/nebula/repo/debian.img",<br>> > target = "xvda1",<br>> > readonly = "no",<br>> > driver = "file:" ] # already tried to change into tap:aio<br>> ><br>> > DISK = [<br>> > type = "swap",<br>> > size = 1024,<br>> > target = "xvda2"]<br>> ><br>> > NIC = [ NETWORK = network ]<br>> ><br>> ><br>> > Content of deployment0<br>> ><br>> > name = 'one-14'<br>> > #O CPU_CREDITS = 256<br>> > memory = '512'<br>> > kernel = '/boot/vmlinuz-2.6.26-2-686-bigmem'<br>> > ramdisk = '/boot/initrd.img-2.6.26-2-686-bigmem'<br>> > root = '/dev/xvda1'<br>> > disk = [<br>> > 'file:/opt/nebula/images/14/images/disk.0,xvda1,w',<br>> > 'tap:aio:/opt/nebula/images/14/images/disk.1,xvda2,w',<br>> > ]<br>> > vif = [<br>> > ' mac=02:00:c0:a8:00:10,ip=192.168.0.16,bridge=xenbr0',<br>> > ]<br>> ><br>> > Logfile :<br>> > cat /var/log/one/14.log<br>> > Fri May 27 11:25:00 2011 [DiM][I]: New VM state is ACTIVE.<br>> > Fri May 27 11:25:00 2011 [LCM][I]: New VM state is PROLOG.<br>> > Fri May 27 11:25:00 2011 [VM][I]: Virtual Machine has no context<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh:<br>> > one:/opt/nebula/repo/debian.img node01:/opt/nebula/images/14/images/disk.0<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: DST:<br>> > /var/lib/one/14/images/disk.0<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: Creating directory<br>> > /var/lib/one/14/images<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: Executed "mkdir -p<br>> > /var/lib/one/14/images".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: Executed "chmod a+w<br>> > /var/lib/one/14/images".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: Cloning<br>> > /opt/nebula/repo/debian.img<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: Executed "cp -r<br>> > /opt/nebula/repo/debian.img /var/lib/one/14/images/disk.0".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_clone.sh: Executed "chmod a+rw<br>> > /var/lib/one/14/images/disk.0".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Creating directory<br>> > /var/lib/one/14/images<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Executed "mkdir -p<br>> > /var/lib/one/14/images".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Executed "chmod a+w<br>> > /var/lib/one/14/images".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Creating 1024Mb image in<br>> > /var/lib/one/14/images/disk.1<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Executed "/bin/dd<br>> > if=/dev/zero of=/var/lib/one/14/images/disk.1 bs=1 count=1 seek=1024M".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Initializing swap space<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Executed "/sbin/mkswap<br>> > /var/lib/one/14/images/disk.1".<br>> > Fri May 27 11:25:42 2011 [TM][I]: tm_mkswap.sh: Executed "chmod a+w<br>> > /var/lib/one/14/images/disk.1".<br>> > Fri May 27 11:25:42 2011 [LCM][I]: New VM state is BOOT<br>> > Fri May 27 11:25:42 2011 [VMM][I]: Generating deployment file:<br>> > /var/lib/one/14/deployment.0<br>> > Fri May 27 11:25:45 2011 [VMM][I]: Command execution fail: 'if [ -x<br>> > "/var/tmp/one/vmm/xen/deploy" ];
