[Users] Dell Poweredge 1955 (blade chassis) power management?
by Nathan Lager 20 Jun '12

20 Jun '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I dont know if this list may have an answer for me or not, but i'm working on adding some older Dell 1955's to a RHEV cluster. Yes, i realize this is the oVirt list, but RedHat's support seems to be at a loss. I cant get power management to work. The blades use an older DRAC interface for power management. I configured this under RedHat Cluster Suite using the old "fence_drac" script. This script is no more on a rhev-h install, and the drac5 script (which works on newer dell blades) does not seem to work on these older systems. Has anyone else had any success with oVirt on these older blades? Might that translate to RHEV? Thanks. - -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk/h10YACgkQsZqG4IN3sumtZwCgoQ/ua2Bt0HmTSAt8O33/gwrR /g0An3EprAg9E6lh1+pP6DUInXA9eu4a =/k26 -----END PGP SIGNATURE-----

[Users] Guest life-cycle
by Dennis Jacobfeuerborn 20 Jun '12

20 Jun '12

Hi, after being able to start my first guest I noticed two things: 1) When I started the guest with the "run once" option the console button didn't become available. Navigating to another section of the GUI and back didn't help. I was only able to make is available by closing the browser tab and then going to the admin portal again from scratch. 2) When my guest froze (due to nested virtualization experimentation that apparently doesn't work yet) I had no (obvious) way to kill the vm. Hitting the stop button apparently only sends a shutdown command but I couldn't find any way to issue a destroy command. After killing the qemu process on the host manually the guest in the portal gui apparently went into an unknown "?" state which isn't surprising but now there seems to be no way to get rid of the vm. What is proper way to get rid of such a misbehaving guest? Regards, Dennis

[Users] SELinux denials on Sanlock
by Trey Dockendorf 19 Jun '12

19 Jun '12

I don't know if this is the wrong place to ask this question, but I just started seeing SELinux denials after adding an iSCSI storage domain in oVirt using my first node. The node is reporting that selinux is preventing /usr/sbin/wdmd from accessing the pid file for that service. Here are the denials type=AVC msg=audit(1340053766.745:7): avc: denied { open } for pid=1908 comm="wdmd" name="wdmd.pid" dev=dm-0 ino=1574530 scontext=system_u:system_r:wdmd_t:s0 tcontext=system_u:object_r:initrc_var_run_t:s0 tclass=file type=AVC msg=audit(1340053766.746:8): avc: denied { lock } for pid=1908 comm="wdmd" path="/var/run/wdmd/wdmd.pid" dev=dm-0 ino=1574530 scontext=system_u:system_r:wdmd_t:s0 tcontext=system_u:object_r:initrc_var_run_t:s0 tclass=file type=SYSCALL msg=audit(1340053766.746:8): arch=x86_64 syscall=fcntl success=yes exit=0 a0=4 a1=6 a2=7fffae656290 a3=fffffff3 items=0 ppid=1 pid=1908 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=wdmd exe=/usr/sbin/wdmd subj=system_u:system_r:wdmd_t:s0 key=(null) I ran restorecon on /var/run/wdmd and it changed from var_run_t to wdmd_var_run_t. I'm not sure how to make sanlock run again to see if that solved the issue. Is there a way to determine it's resolved? Thanks - Trey

[Users] engine-setup fails on NFS ISO Domain

[Users] How can remove the existing isos from engine
by Shu Ming 19 Jun '12

19 Jun '12

Hi, I uploaded several isos to engine by engine-iso-uploader. But, I found that there is no tools to remove the iso from engine or there is no option in engine to remove them. Any clue to remove them? Just remove the iso from the directory where iso domain is mapped? I think it is a bit rude to do that. Is there any graceful way to remove them? -- Shu Ming<shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory

Hi, I created a VM in my engine. And I found that every time I run the VM after shutdown, the VM uuid was changed to a different not while the VM itself was not changed including the VM name. Why doesn't engine keep the UUID for a VM and use the UUID every time the VM starts? How can I persistent my setting to a VM with "vdsClient", like the password set by the "setVmTicket" command? -- Shu Ming<shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory
