similar to: CONFIG_HUGETLB_PAGE in sles 10 domU?

We have some test servers running SLES11SP1 and we''ve updated to the latest kernel from Novell: 2.6.32.13-0.5-xen Since running the updates on these servers our xen ballooning parameters are not working. Because of memory problems in the past we set dom0 to 2048 meg of ram in grub and set the following parameters in /etc/xen/xend-config.sxp: (dom0-min-mem 2048) (enable-dom0-ballooning

I have a sles10 domU running on a sles11 dom0. xen is version 3.4. We''re trying to pass through a scsi card to the domU. We assign the domU the scsi card through virt manager. When we try to boot the domU it won''t boot. We need to update fstab and menu.lst, but we need to boot with the hardware attached to see how it''s being seen by the domU. On a physical machine we

We currently run xen on sles11sp1 and sles11sp2. Our hardware is HP Compaq DL360''s. We originally started with G6''s, but now we''ve grown and have G7''s and G8''s in the mix. We don''t do a lot of live migrations but is convenient to be able to at times. Is there any type of cpu leveling that can be done so live migrations will work with servers

I have several systems running 64bit SLES11SP1. I''m trying to Live Migrate between a couple of them and it''s not working, although the same VM will run on each one starting it manually. The system are not identical. Would one expect migration to work between these two systems? See below. Thanks, James The first system is a ProLiant DL360 G6: Proc 1:2533 MHz Execution

I apologize if this has been asked and answered, but I googled and attempted things for several hours today without success. I have a freshly installed CentOS 7 system that I'd like to disable the firewall and all iptables rules. Basically the equivalent of doing iptables -F In a nutshell I've tried the following commands, in many different ways and orders, but when the system

Hi. I have some new 64bit Windows 2008 R2 domU''s running on SLES11/xen_3.4.2. What is everyone using to get 1gb network performance on win2k8? I''ve used GPLPV on win2k3, but I see you have to sign the drivers yourself for 64bit. Maybe that process isn''t difficult, I only glance at the link from gplpv''s page. What is everyone using? GPLPV is about the only

Wondering if I can get some opinions on dom0 CPU pinning and xm weighting. We have several xen servers on SLES11SP1 and up to this point we have never done anything with pinning CPU''s to dom0. We''re trying to decide if we should be doing that. Same goes for xm weighting (if I''m saying that correctly). For example, running the following command when a xen server

I''m running xen on SLES10SP2. It''s been much more stable than SP1, but I still occasionally have issues. For example, one of my servers (8 CPU/32GB RAM) has five sles pv domUs and five fully virtualized windows 2k3 domUs. It had been up for almost 60 days. Yesterday afternoon one of the sles domU''s stopped responding. I went to check on it and I couldn''t using

I'm trying to use procmail and I'm having trouble getting it to set some headers. I have one mailing list that sets ?Newsgroups: in the header and I want to remove it. I have the following test recipe: :0 * ^Subject:.*\<testing * ^(Mime-Version:|Content-) | formail -IMime-Version: -IContent- If I understand it correctly, it should remove the Mime-Verion and Content headers.

We have implemented hugepage support for guests in following manner In our implementation we added a parameter hugepage_num which is specified in the config file of the DomU. It is the number of hugepages that the guest is guaranteed to receive whenever the kernel asks for hugepage by using its boot time parameter or reserving after booting (eg. Using echo XX > /proc/sys/vm/nr_hugepages).

This patch enables support of hugepages in a pv Xen environment. It is against the latest linux-2.6.18-xen tree on http://xenbits.xensource.com. The patch assumes the guest memory was contiguously allocated on a hugepage-aligned boundary. Future versions of the patch may include checking the hugepage pool and removing hugepages that are not properly aligned. Dave McCracken Oracle Corp.

I had an issue late yesterday where some windows domU''s were down. The person who "owns" those domUs let windows updates install and then restart, which they failed to restart. When I tried to manually restart them I was getting can''t allocate memory errors. In the past I''ve had can''t allocate memory errors when trying to bring up a new domU.

I have xen 3.04 running on SLES10SP1. It''s working great, but I''m wondering if I have some memory issues with dom0. I have 7 domU''s, 1 is win2k, the other 6 are win2k3. I''ve had a lot of machines up and down with a reboot of dom0 in quite a while. I''m wondering if dom0 has not given up memory during the process. I added 5 win2k3 domU''s today.

Sorry for the off topic, but don't a better resource. I'm not great at scripting, but need a quick script to modify a file. I have a long file that has lines like this: some text some text2 CN=DATA.OU=XYZ.O=CO some text3 some text4 And this repeats, but XYZ changes. "DATA" is always called data. (it's being renamed basically) I need to change the middle line but leave

Looking for help kind of in a hurry. I've been searching google but not finding any options. Is there any way to fix missing /dev paths to luns without rebooting? For example, see the output from lsscsi below. The only way I know to fix this is with a reboot, but I REALLY Need to avoid that if possible.

I need to enable some access to the httpd logs over ftp so they can be analyzed by another application to get a report. I used to do this on Windows NT before replacing the server with CentOS. Thanks to help from another thread I have an ftp server enabled on the web server. I thought the easiest thing to do would be to create an id for the application to connect with, then provide a symlink to

This is the latest version of a patch that adds hugepage support to the Xen hypervisor in a PV environment. It is against the latest xen-unstable tree on xenbits.xensource.com. I believe this version addresses the comments made about the previous version of the patch. Hugepage support must be enabled via the hypervisor command line option "allowhugepage". It assumes the guest
