Hi, I have tried this multiple times and i hit the same error.
I have 3 storage domains created (iso, data and export) all connected to the DC with DC status as Up and 1 host with status as Up and the same (only) host acting as SPM.
I used the engine-iso-uploader utility to upload my .iso to the iso domain. Created a new VM and attached a vdisk of type sparse (thin-prov) and click on "Run Once", where i select "Attach CD" and select my .iso, and change boot order to boot from CD, then disk.
But i get this error...
VM first-ovirt-vm is down.

I am unable to figure out why.. bcos the user.group perms for the .iso are fine. In fact i logged into the system serving the nfs share and added 0777 perms still i get the same error. Here is the snip of how the perms for .iso look like...

Does your /var/log/audit/audit.log shows an selinux problem? What's `getenforce`? And `getsebool virt_use_nfs`?
What is `groups qemu`? Does su - qemu -s /bin/bash -c 'strings your.iso' work for you?
Regards, Dan.
Hello Dan, Here is the output you requested...
[root@llm56 ~]# ls -lZ /rhev/data-center/4087fea7-b54a-4318-8d5c-828eff8846f4/35f880f8-bd0c-4063-b171-2ddaa59e1212/images/11111111-1111-1111-1111-111111111111/Fedora-16-x86_64-DVD.iso -rwxr-xr-x. vdsm kvm system_u:object_r:nfs_t:s0 /rhev/data-center/4087fea7-b54a-4318-8d5c-828eff8846f4/35f880f8-bd0c-4063-b171-2ddaa59e1212/images/11111111-1111-1111-1111-111111111111/Fedora-16-x86_64-DVD.iso
[root@llm56 ~]# getenforce Enforcing
[root@llm56 ~]# getsebool virt_use_nfs virt_use_nfs --> off
[root@llm56 ~]# groups qemu qemu : qemu kvm
Also `su - qemu -s /bin/bash -c 'strings your.iso'`
worked for me.. dumped loads of strings on the screen.
_______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users Perhaps I missed that snippet of logs, but is llm56 the hyper-visor?
Also, here is another litmus test to help shake out some common NFS issues. Do the following from the hyper-visor: 1. temporarily give user vdsm in /etc/passwd a login shell (e.g. /bin/bash) 2. mkdir /mnt/testmount 3. mount <nfs server here>:/path/to/iso/storage/domain /mnt/testmount 4. su - vdsm <-- Really important. 5. cd 35f880f8-bd0c-4063-b171-2ddaa59e1212/images/11111111-1111-1111-1111-111111111111 6. touch test.txt 7. strings Fedora-16-x86_64-DVD.iso 8. reset vdsm in /etc/passwd to nologin
Do 6 and 7 work?
Cheers, Keith
Here another suggestion, a tool, nfs-check: http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=blob_plain;f=contrib/nfs-check.p... -- Cheers Douglas
