Xen Security Update - XSA-{268,269,272,273}
Dear Security Team, I have prepared a new upload addressing a number of open security issues in Xen. Due to the complexity of the patches that address XSA-273 [0] the packages have been built from upstream's staging-4.8 / staging-4.10 branch again as recommended in that advisory. Commits on those branches are restricted to those that address the following XSAs (cf. [1]): - XSA-273

Test report xen_4.11.1~pre.20180911.5acdd26fdc+dfsg-2
I'm just dumping all I got in here, after initial feedback we can see how to organize todo's around it. tl;dr: * Does not upgrade cleanly from 4.8 packages, so we have to prevent this from entering testing until we fix that. * Live migration is broken, explodes with memory allocation errors. ---- >8 ---- 1. Build packages * I have built salsa/master using pbuilder targeting sid.

Re: xen and libvirt
Hi I need the e820_host option for a passthrough of an digitaldevices dvb-s2 card. Without this I'cant initialize the card in the domU. On an all my domU's with high IO load like an file server I need to set max_grant_frames = 64 or higher. Without this I get a lot of messages on dom0/domU and kernel exceptions. I've read it should be ok to set it = 256 on all domU's

xen and libvirt
Hi Does someone know how it is possible these parameters: e820_host max_grant_frames to set with libvirt xml config? I use them with xl config but I want to change to libvirt config/tools. (with libvirt 4.10 it is possible to start pvh domains) -- ------ Greetz

Nested Virtualization on Google Cloud.
I am using nested virtualization on a Google Cloud Compute instance. Things are generally working fine with libvirt using qemu+kvm, however I observed that <cpu mode='host-model'> is not exposing avx and avx2 instruction set to the guest Linux instance. Google Cloud platform claims the CPU model of the host compute instance is Broadwell, however libvirt capabilities maps it to

[PATCH v2 1/2] xenconsoled: use grant references instead of map_foreign_range
Grant references for the xenstore and xenconsole shared pages exist, but currently only xenstore uses these references. Change the xenconsole daemon to prefer using the grant reference over map_foreign_range when mapping the shared console ring. This allows xenconsoled to be run in a domain other than dom0 if set up correctly - for libxl, the xenstore path /tool/xenconsoled/domid specifies the

Xen PVH support for grub-xen in Buster
Hi Debian Grub maintainer, In december, Xen PVH support has been committed in grub master: https://www.mail-archive.com/grub-devel at gnu.org/msg28125.html The last pieces needed in the Linux kernel to boot PVH with grub2 landed in Linux 4.20. I asked our kernel team to carry those patches on top of the Linux 4.19 kernel that is going to ship in Buster, and that wish was granted:

How to extract all rows that contain the value of X in any column?
Hi R-helpers, I'm trying to use this code > pvh_dnv<-pvh[sapply(pvh=="dnv"),] to make a new dataframe containing the rows from pvh that contain the value of "dnv" in ANY column. But, it's not working. I get this error Error in match.fun(FUN) : element 1 is empty; the part of the args list of 'is.function' being evaluated was: (FUN) which, to

Xen-kernel: Update to 4.14 or 4.19?
Hey all, We've been on 4.9 for some time now, and while it's still supported, I think it's time to start thinking about upgrading, and I'd like input from the community about which version to move up to. 4.19 has been out for almost 5 months now. It will include PVH domU support, and PVH dom0 support in what _is believed_ to be the final form; so when the Virt SIG moves to a

PVH questions
Hello, I''ve had a look at PVH support, and I have a few questions: - events are still dispatched the PV way through the callback, right? - I guess FPU errors don''t trigger an INT13, so I don''t need to handle that? - How about the console and store MFNs from the boot info? Are they still MFNs, or actually PFNs? - How about PV network in non-copy mode? It used to be

How to use PVH mode in xen
Hi, I'm instresting with the PVH mode, is there any wiki available to boot up a PVH guest? I used the following source code to compile the xen and dom0. I have tried adding pvh=1 in xl.cfg file as pv mode, but guest still uses qemu device model. This patch series can also be pulled from this git tree: git://xenbits.xen.org/people/gdunlap/xen.git out/pvh-v15 The kernel code for PVH guests

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

[PATCH RFC v2] pvh: clearly specify used parameters in vcpu_guest_context
The aim of this patch is to define a stable way in which PVH is going to do AP bringup. Since we are running inside of a HVM container, PVH should only need to set flags, cr3 and user_regs in order to bring up a vCPU, the rest can be set once the vCPU is started using the bare metal methods. Additionally, the guest can also set cr0 and cr4, and those values will be appended to the default values
