Yeah, Dominique, your wiki was one of the many docs I read through before/during/after starting down this primrose path... thanks for writing it. I'm an Arch user, and I couldn't find anything to indicate qemu, as its compiled for Arch, will look in /etc/default/qemu-kvm. And now that I've got the right page size, the instances are starting... The reason I want to use the page element

I realize this falls under the category of "so incredibly vague I should maybe not send it", so I have low expectations and apologize beforehand if it's just pure noise. That being said - it appears that the whole HOST system becomes laggy. It can effect the mouse, the keyboard, the network. There are no messages in the logs that I can find that indicate the system is blocked or

*facepalm* Now that I'm re-reading the documentation it's obvious that <page/> and @nodeset are for the guest, "This tells the hypervisor that the guest should have its memory allocated using hugepages instead of the normal native page size." Pretty clear there. Thank you SO much for the guidance, I'll return to my tweaking. I'll report back here with my results.

Hello All, I'm trying to enable hugepages, I've turned off THP (Transparent Huge Pages), and enabled hugepages in memoryBacking, and set my 2MB hugepages count via sysctl. I'm getting "libvirtd[5788]: Failed to autostart VM 'atlas': internal error: Unable to find any usable hugetlbfs mount for 16777216 KiB" where atlas is one of my guests and 16777216 KiB is the

I've just noticed that I'm having issues with finding files using "locate" when those files are on btrfs subvolume mounts. The issue is that updatedb cannot discern the difference between a btrfs bind mount and btrfs subvolume [1]. This generally means that if you're using btrfs subvolume mounts and updatedb at the same time, and you want to index those subvolumes,

As I mentioned, I got the instances to launch... but they're only taking HugePages from "Node 0", when I believe my setup should pull from both nodes.

Regarding fine tuning my explanation about what system does de actual mounting of Hugepages, you?re probably right?. Thanks for the correction. On upstart systems (like Ubuntu) the mounting of Hugepages is done by the init script qemu-kvm.conf Van: G.

First I'll quickly summarize my understanding of how to configure numa... In "//memoryBacking/hugepages/page[@nodeset]" I am telling libvirt to use hugepages for the guest, and to get those hugepages from a particular host NUMA node. In "//numatune/memory[@nodeset]" I am telling libvirt to pin the memory allocation to the guest from a particular host numa node. In

Hi, I’m struggling with virsh not detecting my hugepage mount. I have the following kernel command line: BOOT_IMAGE=/vmlinuz-4.8.13-gentoo root=/dev/mapper/gensd-gentoo ro quiet splash intel_iommu=on video=efifb:off,vesafb:off,simplefb:off splash=verbose,theme:livedvd-aurora kvm.ignore_msrs=1 transparent_hugepage=never hugepages=3072 softlevel=qemuvm My startup script outputs the following:

Did you create a mount for the hugepages? If you did, that's maybe the problem. I did that also at first but with libvirt it isn't necessary and in my case, it broke hugepages... If I'm not mistaking, libvirt takes care of the hugepages mount. A while ago, I've written a wiki to use hugepages in libvirt and Ubuntu. https://help.ubuntu.com/community/KVM%20-%20Using%20Hugepages

Hi all, I am trying to install nested Esxi 6.x under a Centos7 kvm host to use it as test lab for new ESXi versions, but I am doing something wrong because I can't install it. I have configured kvm and kvm_intel modules with the following options: options kvm ignore_msrs=1 options kvm_intel nested=1 ept=1 and I add the following options in <cpu> xml guest file: <cpu

Hello all, I am having trouble running a count function in R using RODBC to query a table I created in Oracle. It may very well be that my SQL coding is incorrect; I just started learning it. But if someone could point me in the right direction or tell me if I am going about this the correct way that would be greatly appreciated! The script I have right now is: >require(RODBC)

Hello all, I have two questions. One probably has a very simple answer but I have checked the FAQ, other websites and still have not found an answer. I am new to using R. My very simple question is how to do line breaks when creating an axis title (xlab) ? I have a few that are too long and they get cut off... I found on the internet the "/n" function but I think I must be using it

Hello, I am constructing a boxplot but have a very wide range of values (zero - ~28000). I have placed an axis break at the 8000 mark but would like to have a different scale above the break that ranges from 8000-28000. Right now my axis is so large that the boxplots are only represented as lines with the outliers above. Does anyone know where I could find code that explains how to do this?

I recently read about the following new technologies from Digium. Has anyone tried the new HPEC or knows when it will be available? TDM800P and HPEC The TDM800P is an 8-port analog telephony interface card, so it fills the gap between Digium's 4-port and 24-port cards. Analog phones and POTS lines are going to be with us for some time, and demand for support for them remains high. The
