The self_nmi() code cause''s an NMI to be triggered by sending an APIC message to the local processor. However, NMIs are blocked by the VMEXIT, until the next iret or VMENTER. Volume 3 Chapter 27 Section 1 of the Intel SDM states: An NMI causes subsequent NMIs to be blocked, but only after the VM exit completes. As a result, as soon as the VMENTER happens, an immediate VMEXIT happens

I have read thru what other users have tried in this list when they have experienced seemingly similar issues to what I have, without success. I suspect there might be an issue regarding both the X100P and TDM04b cards being used in an Intel SE7525GP2 motherboard, as I had to even wait for a BIOS update from Intel in order to utilize my 3ware 9500 SATA raid controller on it (3ware Kb -->

I''ve been banging my head against this wall for several hours, and it hurts now so I''ll stop and ask someone. In one of my forms I had been using a statement to extract the current year for use with some form field calculations. <% currentyear = DateTime.now.year %> And then further down several date_selects like the following, <%= date_select

I have incoming PSTN lines on an Adtran 750 channel bank. Calls are evaluated by an agi script based on callerid and forwarded to an international DID through Voxee. There is an IVR at that number that asked to user to enter a selection. When the user presses a key, my pbx puts the call on hold and tries to start music on hold. What's doing this? I have no backgrounds, no listen, the call

Hi, My bosses are running into an issue, where we type "ls" on a nfs mounted filesystem, and files that are there are not listed... I thought it was pilot error until my big boss showed me... but we can vi the files, we can access them via other means if we know the name. Then once we have accessed them, LS now shows the files. We are running centos 6.5, we are accessing them via

I have samba+ads working fine *HOWEVER* when I run net ads keytab create it fails. Using -d 10 the debug output says it cannot write to the file. This is truly bizarre as I am running this as root! e.g. # /usr/local/opt/samba/samba-3.0.24/bin/net ads keytab create ; echo $? 183 And /usr/local/opt/samba/samba-3.0.24/bin/net -d 10 ads keytab create ; echo $?

I have 19 servers with this smb.conf share definition working: [export] comment = Exported Files path = /tmp/export guest ok = Yes On the 20th server however, this just doesn't want to work. I've gone through the basics of guest access and permissions more than a few times trying to figure this one out. Approaching this from another angle, I tried the following

Hi all, I am trying to set processor affinity for a specific process using a shell script without result. Script: #!/bin/sh -x cpu_affinity_ok="2" cpu_affinity="taskset -p -c `cat /tmp/test.pid` | awk '{print $6}'" if [ -f /tmp/test.pid ]; then if [ "$cpu_affinity" == "$cpu_affinity_ok" ]; then exit 0 else taskset -p -c 2

Hello, i am running CentOS 5.4. i have a requirement where i need to have 1 application have a single processor all to its self, and the rest of the system run on the other processors. "taskman" lets me bind the process to a processor(s), but it does not make it exclusive. Is this possible to do? i have even tried mucking around with the rc.sysinit, but to no avail. thank you very

Lots of 3D games such as Team Fortress 2, Audiosurf or Stalker have very low performance in comparison to running on the same computer on Windows. What can I do to improve it? What developers have still to implement to fully support 3D rendering?

Hi. Can anyone confirm if vcpupin works correctly with kvm? If set I pin a vcpu it shows up correctly via vcpuinfo, but querying via taskset shows the cpu is not pinned.

Dear ML We upgraded a Dell Poweredge PE 1950 Server the 8th of May. Since then the server rebooted 3 times without external cause (it is located in a server farm with redundant power supply etc.). Looking at the servers monitoring infrastructure with Dell's own OpenManage tools, I get strange errors: [root at servernew ~]# omreport system esmlog (....) Severity : Critical Date

Hello Is it correct that IAX2 uses more CPU, than SIP? Also, can it be true that IAX2 is much more sensitive against high CPU loads? Also, does Asterisk support and use multiprocessor architectures, such as Xeon? ? Regards Jon -- No virus found in this outgoing message. Checked by AVG Free Edition.

Hi everyone, I would like to ask what the current status of FLR, or better of FLR emulation is in latest Xen and if we can expect better support in the future. I''m asking because with xl (latest build and traditional qemu, not upstream), I always had problems with rebooting domUs which have vga cards passed through to them, because appearently they don''t get reinitialized and

Hi I tried to restrict usage of some running VM by cpu.shares (i.e. set to 10 from original 1024) on loaded system and it seem doesn't work as I expected... all running processes has same CPU usage (by htop) :-/ Does anyone has same experience?

Hello, I am currently running R on ubuntu and everything is working perfectly fine. However, I would like to connect to R via Windows using Eclipse StatEt plugin. Is this possible to do? or do I have to have a version of R running on Windows also? I prefer to have Linux do the heavy lifting and Windows Eclipse to be a sort of GUI. Any thoughts?
