Working with different OSs can be quite challenging (mentally :-)). I wonder why the command "halt" has not same result between EL6 and EL8. To shutdown the vm or workstation in EL8 i must use "shutdown now". Who mandates this behavior in terms of configuration file? -- Leon

Hi, I've been making some tests with libvirt and LXC and found some problems when halting/restarting a LXC container from within. Basically, on a Ubuntu 12.04 system with libvirt installed as package (0.9.8), I've created a basic container image with: lxc-create -t ubuntu -n lxc And started it using the libvirt XML listed below and the following command: virsh -c lxc:// create

Working with different Linux Distributions makes the life harder. So far I have found out that 'poweroff' & 'reboot' has the same behaviour on Linux/Unix/BSDs.

Can poweroff.c32 do the same as sudo halt -p in ubuntu?

Hey folks, In a recent blog post, John Regehr pointed out that LLVM is currently optimizing away read-only functions containing infinite loops whose return values are never used. The culprit for the moment is the inliner, but the more insidious problem is that isTriviallyDeletable currently returns true for any read-only function whose value is not used. In order to prevent this from happening

There is a problem with the patch I sent out yesterday. The patches for the glm code are applied in the wrong place. I have removed the patch file and will have a real one available latter today.

Hi, I have set-up the ups shutdown feature provided by Red Hat /etc/rc.d/init.d/halt script, which will issue a "upsdrvctl shutdown" command just before powering off the system. It appears that this command fails as if the driver is not available. I wonder whether the usb driver / stack is still available at this very late stage ? If not available then does it mean one cannot

...er images in a loop using GDAL. The thing is that releasing this command in the bash results in the following error Error in function (handle) : GDAL Error 1: TIFFReadDirectory:/tmp/RtmpPCALnL/file265f67a6: cannot handle zero scanline size Calls: <Anonymous> -> .Call Execution halted The scripts halts, although there are more images to process. The question is why the script halts and why the script is not halted (but still "decorated" with errors) when releasing it within the R console like so R CMD source("/data/myscript.R") The result of this R CMD...

This patch adds base para-virtualization support to the queue spinlock in the same way as was done in the PV ticket lock code. In essence, the lock waiters will spin for a specified number of times (QSPIN_THRESHOLD = 2^14) and then halted itself. The queue head waiter, unlike the other waiter, will spins 2*QSPIN_THRESHOLD times before halting itself. Before being halted, the queue head waiter will set a flag (_Q_LOCKED_SLOWPATH) in the lock byte to indicate that the unlock slowpath has to be invoked. In the unlock slowpath, the c...

Setting up nut on a system where an LVM volume holds the root filesystem.. What is the appropriate device form to use with "mdadm --readonly" in halt? This is on a CentOS 5 system. So far I have found three possibilities, but I do not know which one (if any) will still be valid that late in the halt procedure: 1. /dev/md0 (from posts on the net) 2.
