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

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

9d1fd58ff602 was bogous in not letting a new domain being created if its scheduling parameters --when running under the sedf scheduler-- were not fully specified, making creation fail like in this example here below: 2012-06-16 07:37:47 Z executing ssh ... root@10.80.248.105 xl create /etc/xen/debian.guest.osstest.cfg libxl: error: libxl.c:3619:sched_sedf_domain_set: setting domain sched sedf:

Hello, Third version of the NUMA placement series Xen 4.2. All the comments received during v2''s review have been addressed (more details in single changelogs). The most notable changes are the following: - the libxl_cpumap --> libxl_bitmap renaming has been rebased on top of the recent patches that allows us to allocate bitmaps of different sizes; - the heuristics for deciding

Under the assumption that in these cases recurring faults aren''t a security issue and it can be expected that the drivers there are going to try to take care of the problem.

Hi, I installed xen using yum in fedora 16. When I boot grub shows me a lot xen botting options. Are the all same or have different funtionality? also in xl info I have xen_changeset : unavailable, what does it mean? I also can not copy host CPU configuration in guest, it gives Error copying host CPU: No host CPU reported in capabilities Traceback (most recent call last): File

Hi, list, A VMM provides a VMCS for each VM. How does the VMM assign system resources for each VM? For example, in a multi-core environment, how can I enable the VMM to run, say, on a two-core intel''s processor while I am able to force a VM to execute only on a specific core upon initializing the Guest OS ? that is to say, how I can assure the VM to believe that there is only one physical

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

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 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

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

Team I have a Dell PowerEdge R720xd, with the Broadcom NetXtreme bcm5720. I found the following thread: http://forums.freebsd.org/showthread.php?t=31769 I find I am unable to use the NIC's (there are 4 on the server). When we put a cable into it we get a "watchdog timeout -- resetting" error, and the machine will pause for 5 or so seconds. IP may or may not come up randomly.
