So that we can easily figure out whether or not we are running a debug build of Xen (e.g., via `xl dmesg''). Signed-off-by: Dario Faggioli <dario.faggioli@citrix.com> --- Changes from v1: * moved the #ifndef-ery around variable definition; * repositioned the "debug=%c" outside of the ''compiled-by'' section. diff --git a/xen/drivers/char/console.c

Hello, I observed that a configuration where dom0 vcpus were pinned to a set of pcpus in the host using dom0_vcpus_pin and the guests were prevented from running on the dom0 pcpus (here called "exclusively-pinned dom0 vcpus", or xpin) caused the general performance of the guests in a host with around 24 pcpus or more to increase during bootstorms and high density of guests, even

Hi, I am trying to install xen and provide libvrit support to it but while installing at some point of time it tries to connect to GIT repository and creates a clone but I am behind firewall and it is getting timed out.... :( I am pasting a screenshot below. Can anyone of you please help me out with this one. // Varun

This information will be mirrored on the Xen 4.4 Roadmap wiki page: http://wiki.xen.org/wiki/Xen_Roadmap/4.4 We''re nearly to the completion of the code freeze, scheduled for tomorrow. After the code freeze, only bug fixes and features marked as "blockers" will be considered. At the moment, the only feature considered a blocker is experimental PVH dom0 support. In early RCs,

Hello, I have asked this question in Xen-users mailing list too. But since it involves compiling from source, I realised asking this here makes more sense. Please forgive me for the spam. I am relatively new to Xen and need help compiling and installing Xen from source. Using some tutorials online, I have got Xen working with the ''yum install xen'' method. I used virt-manager

No it was not booted with xen kernel. Actually I tried booting it with xen kernel but I am getting a message saying Error No 15 : File not found. I tried editing the grub entry and noticed that there are 3 entries: 1) kernel /boot/xen.gz vga= mode-0x345 2) module /boot/vmlinuz-3.0.13-0.27-xen....... 3) module /boot/initrd-3.0.13-0.27-xen And in /boot i listed down the files, only xen.gz is there.

Hello everyone, Reposting with after having applied the (minor) fixes suggested by Wei and Jan. Allen, if you can tell us what you think about this, or suggest someone else to ask some feedback to, if you''re no longer involved with VT-d, that would be great! :-) -- As already discussed here [1], dealing with IOMMU faults in interrupt context may cause nasty things to happen, up to

Hi all, This is the second take of a patch that I submitted some time ago for allowing specifying vcpu pinning taking NUMA nodes into account. IOW, something like this: * "nodes:0-3": all pCPUs of nodes 0,1,2,3;  * "nodes:0-3,^node:2": all pCPUS of nodes 0,1,3;  * "1,nodes:1-2,^6": pCPU 1 plus all pCPUs of nodes 1,2    but not pCPU 6; v1 was a single patch, this is

Hello, This small series deals with some weirdness in the mechanism with which the credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are available in the changelog of the first patch. The new approach has been extensively benchmarked and proved itself either beneficial or harmless. That means it does not introduce any significant amount of overhead and/or performances

Hi all, These days I installed xen 4.3 unstable from source and recompiled qemu upstream with spice support. After xl create , the windows domU started successfully and spice client can visit the VDI. However, it display blue screen before entering the windows welcome screen. Is it a bug in current upstream qemu support? My domU configuration file is: builder =

hi, thanks for your response. i cleaned that above one and installed in this following steps: * sudo apt-get install gcc make pkg-config libxml2-dev libgnutils-dev libdevmapper-dev libcurl4-gnutls-dev python-dev libpciaccess-dev libxen-dev libnl-dev * ./configure = --prefix=/usr --localstatedir=/var --sysconfdir=/etc --with-xen=yes --with-libxl=yes * make * make install now i am getting the

Hi Ian-s, Two small patches for OSSTest. The first one turns on compiling the Linux modules for MegaRAID SAS, needed for the ultralisk machine in the Cambridge lab. The second adds an entry in the README file about the RebootTimeExtra host property, which I also needed to use for ulttralisk, as scrubbing 368GB of RAM really takes a lot! git://xenbits.xen.org/people/dariof/osstest.git misc Let

Hi, I have a question about the memory layout of the Xen hypervisor, dom0 and domU. *The goal I want to achieve is: I want to show which RAM area is used by hypervisor, which RAM area is used by dom0, which RAM area is used by each domU (PV guest domain). I hope to know the above information when xen is booted as well as when xen is running some domUs. I already know that we can dedicate a fix

i installed both xen-4.2.1 and libvirt-1.2.0 from the source only. i moved with the latest version of libvrirt. i did the gdb in libvirt-1.2.0 and i raised the bug.
