Hi Carlos. Very strange: After running ttylinux and enabling the saveas-feature ('onevm saveas 318 0 "318_archived"') I get the following error message (vm.log) after deleting this instance: Thu Feb 10 12:24:31 2011 [VMM][W]: Ignored: CANCEL SUCCESS 318 Domain one-318 destroyed Thu Feb 10 12:24:31 2011 [HKM][I]: Command execution fail: /srv/cloud/one/share/hooks/image.rb 318 Thu Feb 10 12:24:31 2011 [HKM][I]: STDERR follows. Thu Feb 10 12:24:31 2011 [HKM][I]: ExitCode: 255 Thu Feb 10 12:24:31 2011 [HKM][E]: Error executing Hook: image.
After debugging $ONE_LOCATION/share/hooks/image.rb there might be a problem with the proper image location: line 75 in $ONE_LOCATION/share/hooks/image.rb (result = img_repo.update_source(image, source_path) outputs "No such file or directory - /srv/cloud/one/var/318/disk.0 or /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12" All disk images of my vm's are deployed to $ONE_LOCATION/var/<vm_id>/images/ If I get the error message right, it tries to lookup for the disks in $ONE_LOCATION/var/<vm_id>/ I need your help. Can that be right? (detailed logs see below) Thanks in advance Marco $ cat ttylinux.one ############################################################################### NAME = ttylinux CPU = 0.1 MEMORY = 64 DISK = [ source = "/srv/cloud/one/testing/ttylinux.img", target = "hda", readonly = "no" ] FEATURES=[ acpi="no" ] GRAPHICS = [ type = "vnc", listen = "0.0.0.0", port = "5901" ] $ onevm create ttylinux.one ############################################################################### $ onevm list ############################################################################### ID USER NAME STAT CPU MEM HOSTNAME TIME 318 oneadmin ttylinux runn 0 0K testbed07 00 00:00:08 $ onevm show 318 ############################################################################### VIRTUAL MACHINE 318 INFORMATION ID : 318 NAME : ttylinux STATE : ACTIVE LCM_STATE : RUNNING START TIME : 02/10 12:20:34 END TIME : - DEPLOY ID: : one-318 VIRTUAL MACHINE MONITORING NET_TX : 0 NET_RX : 0 USED MEMORY : 0 USED CPU : 0 VIRTUAL MACHINE TEMPLATE CPU=0.1 DISK=[ DISK_ID=0, READONLY=no, SOURCE=/srv/cloud/one/testing/ttylinux.img, TARGET=hda ] FEATURES=[ ACPI=no ] GRAPHICS=[ LISTEN=0.0.0.0, PORT=5901, TYPE=vnc ] MEMORY=64 NAME=ttylinux VMID=318 $ ls -la var/318/ ############################################################################### total 24 drwxrwxrwx 3 oneadmin cloud 75 2011-02-10 12:20 . drwxr-xr-x 323 oneadmin cloud 8192 2011-02-10 12:20 .. -rw-r--r-- 1 oneadmin cloud 416 2011-02-10 12:20 deployment.0 drwxrwxrwx 2 oneadmin cloud 38 2011-02-10 12:20 images -rw-r--r-- 1 oneadmin cloud 104 2011-02-10 12:20 transfer.0.prolog -rw-r--r-- 1 oneadmin cloud 1266 2011-02-10 12:20 vm.log $ ls -la var/318/images/ total 40964 drwxrwxrwx 2 oneadmin cloud 38 2011-02-10 12:20 . drwxrwxrwx 3 oneadmin cloud 75 2011-02-10 12:20 .. -rw-r--r-- 1 oneadmin cloud 416 2011-02-10 12:20 deployment.0 -rw-rw-rw- 1 oneadmin cloud 41943040 2011-02-10 12:21 disk.0 $ onevm saveas 318 0 "318_archived" ############################################################################### $ onevm show 318 ############################################################################### VIRTUAL MACHINE 318 INFORMATION ID : 318 NAME : ttylinux STATE : ACTIVE LCM_STATE : RUNNING START TIME : 02/10 12:20:34 END TIME : - DEPLOY ID: : one-318 VIRTUAL MACHINE MONITORING NET_TX : 0 NET_RX : 0 USED MEMORY : 0 USED CPU : 0 VIRTUAL MACHINE TEMPLATE CPU=0.1 DISK=[ DISK_ID=0, READONLY=no, SAVE=YES, SAVE_AS=37, SOURCE=/srv/cloud/one/testing/ttylinux.img, TARGET=hda ] FEATURES=[ ACPI=no ] GRAPHICS=[ LISTEN=0.0.0.0, PORT=5901, TYPE=vnc ] MEMORY=64 NAME=ttylinux VMID=318 $ oneimage show 37 ############################################################################### IMAGE INFORMATION ID : 37 NAME : 318_archived TYPE : OS REGISTER TIME : 02/10 12:22:50 PUBLIC : No PERSISTENT : No SOURCE : /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12 STATE : disa RUNNING_VMS : 0 IMAGE TEMPLATE DEV_PREFIX=hd NAME=318_archived $ ls -la /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12 ############################################################################### ls: cannot access /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12: No such file or directory $ onevm delete 318 ############################################################################### $ onevm list ############################################################################### ID USER NAME STAT CPU MEM HOSTNAME TIME $ oneimage show 37 ############################################################################### IMAGE INFORMATION ID : 37 NAME : 318_archived TYPE : OS REGISTER TIME : 02/10 12:22:50 PUBLIC : No PERSISTENT : No SOURCE : /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12 STATE : rdy RUNNING_VMS : 0 IMAGE TEMPLATE DEV_PREFIX=hd NAME=318_archived $ ls -la /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12 ############################################################################### ls: cannot access /srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12: No such file or directory $ cat $ONE_LOCATION/var/318/vm.log ############################################################################### Thu Feb 10 12:20:36 2011 [DiM][I]: New VM state is ACTIVE.
