similar to: Bus error while allocating hugepages in domain 0

Hi, I have allocated few order=9 pages in Xen memory space using alloc_domheap_pages(NULL,9,0) during boot time just before domain is created (dom0 = domain_create(0, DOMCRF_s3_integrity, DOM0_SSIDREF) in xen/arch/x86/setup.c). I got the following virtual addresses in xen log message- (XEN) a2k2: Virt_addr:ffff83011cc00000 MFN:11cc00 (XEN) a2k2: Virt_addr:ffff83011ca00000 MFN:11ca00 (XEN)

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).

Hi all, When i create a group in AD and adds users in the same than with #getent group i can see the group and its members properly.

But i

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.

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

So basically you're saying that this THP feature is broken for CentOS 7 ? The feature is enabled by default. Is there a thread opened on this issue ? ?n mie., 24 aug. 2016 la 18:13, <m.roth at 5-cent.us> a scris: > Laurentiu Soica wrote: > > Hello, > > > > I have a CentOS 7 installation on baremetal with 2 CPUs, 10 cores each > and > > HT enabled, 128 GB

Hello! In our experiment, we are trying to mark IP packets at a source host. Some of these packets have a 28-byte "IP Options" field, hence a 48-byte IP header. We observed (using ethereal) that the tc script at the source appropriately marks the packets that DO NOT have an "IP Options" field (i.e., regular 20 byte header), however, all the packets with the "IP

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
