If you're one of the people who has cvsup'd to 4.8-stable since August 8th and you've since begun to experience panics on a previously stable system, please apply the attached patch and see if your previous stability has been restored. Please tell me your results. Thanks, Mike "Silby" Silbersack -------------- next part -------------- diff -u -r

This helps the introspection tool with the VGA to GPA translations without the need to monitor the guest page tables.

In FreeBSD 4.7 and 4.8, the code for vm_object_allocate() in the file /usr/src/sys/vm/vm_object.c looks like: > 232 vm_object_t > 233 vm_object_allocate(type, size) > 234 objtype_t type; > 235 vm_size_t size; > 236 { > 237 vm_object_t result; > 238 > 239 result = (vm_object_t) zalloc(obj_zone); > 240 > 241

Good Day, Please cc me ( eperrin@cseven.ca ) on responses to this, I am not on either mailing list anymore. I cvsup'ed on the STABLE branch today (September 9th) at around 2:30PM EDT. No problems with buildworld or kernel build, but I am getting failures during installworld Error and output from uname -a are below. vm/pmap.h -> vm/pmap.ph vm/swap_pager.h -> vm/swap_pager.ph vm/vm.h

From: ?tefan ?icleru <ssicleru at bitdefender.com> The introspection tool uses this function to check the hardware support for EPT switching, which can be used either to singlestep vCPUs on a unprotected EPT view or to use #VE in order to avoid filter out VM-exits caused by EPT violations.

Hello! I''m working on a guest OS port which uses NetBSD drivers, and I''m currently working on the netfront support. I''m basing the driver on the FreeBSD 7.0 driver, and I''ve run into a problem in network_alloc_rx_buffers. Parts of the code with line numbers is given below, and I''ll try to explain where the problem occurs. The basic problem is that

This event is send by the vCPU thread and has a low priority. It will be sent after any other vCPU introspection event and when no vCPU introspection command is queued.

Occasionally stopping amd freezes my system. It's a rare occurrence, and I haven't found a reliable way to reproduce it. It's also a real freeze, so there's no way to get into the debugger or grab a core dump. I only can perform the 4 seconds hard shutdown to revive the system. I run amd through sysutils/automounter, which is a scripting solution that generates an amd.map file

Hello, The Xen community is working on a new virtualization mode (or maybe I should say an extension of HVM) to be able to run PV guests inside HVM containers without requiring a device-model (Qemu). One of the advantages of this new virtualization mode is that now it is much more easier to port guests to run under it (as compared to pure PV guests). Given that FreeBSD already supports

This patch series is based on the VM introspection patches (https://lore.kernel.org/kvm/20200721210922.7646-1-alazar at bitdefender.com/), extending the introspection API with EPT Views and Virtualization Exceptions (#VE) support. The purpose of this series is to get an initial feedback and to see if we are on the right track, especially because the changes made to add the EPT views are not small

The problem occurs after an update of 8-stable from r248120 to r252111. Sometimes shutdown hangs: Waiting (max 60 seconds) for system process `vnlru' to stop...done Waiting (max 60 seconds) for system process `bufdaemon' to stop...done Waiting (max 60 seconds) for system process `syncer' to stop...

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
