similar to: How does vmm get all mmio areas of pci devices?

Hi all, I'm trying to develop some applications that communicate with VMM about guest OSs. Libvirt has drivers for many VMMs like Qemu, Vbox, etc. I'm currently using Vbox and time to time I get the error that says "this function is not supported by the connection driver". So, for which VMM, libvirt has the most compatible driver, regarding your experiences? Kind regards Kadir

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, Please can anybody explain how communication(direct or indirect) happens between xen and guest os(windows) in full virtualization mode. Both from VMM to guest and from guest to VMM. Thanks and regards, Aditya. __________________________________________________________ Yahoo! India Answers: Share what you know. Learn something new http://in.answers.yahoo.com/

Hi guys: I'd like to "scriptify" my virtual machine manager deployment. In particular id like to 1) Configure a 3 node cluster from an ISO 2) Assign static IPs at the vm level, and have those cascade into /etc/hosts 3) Add storage to each machine in the cluster . 4) Set the memory/CPU# for each machine. Is there a way i can automate this task using VMM, or maybe, using VMM in

Turing introduced a new simplified page kind scheme, reducing the number of possible page kinds from 256 to 16. It also is the first NVIDIA GPU in which the highest possible page kind value is not reserved as an "invalid" page kind. To address this, the invalid page kind is made an explicit property of the MMU HAL, and a new table of page kinds is added to the tu102 MMU HAL. One

Hi Ben, I've been working with an mmio-constrained pci hierarchy intended almost solely for nvme devices and switches. Binding nouveau to an NV50-based gpu results in a kernel panic as the device cannot be fully mapped. I've made modifications in nv50 and vmm to unbind the driver from this hierarchy, and modified gf100 assuming it will have the same issue. 1/4 also includes a fix where
