[Xen-devel] Xen Nested Virtualization for HyperPlatform

2017-11-09 Thread Kangjie Xi
Hi, I am researching HyperPlatform(https://github.com/tandasat/HyperPlatform) recently, it is a thin hypervisor based on Intel VT-x and EPT technology, it can't create a new virtual machine but just turns the already running Windows OS into its guest VM. HyperPlatform works very well in VMware VM

[Xen-devel] Restore PVHVM DomU with a different MAC

I reproduce the issue again, and attachments are the log. # xl dmesg > xldmesg.log # dmesg > dmesg.log However there is not error in the log. Maybe just as you said, the nested virtualization is not mature. Do you know how much work to do to change the Xen source code, to make Xen support host-o

I have asked the related issue on xen-users list (https://lists.xenproject.org/archives/html/xen-users/2017-05/msg00090.html), it has detail on hangs, if you want more detail, I can reproduce the problem and send you more info. HyperPlatform and SimpleVisor can work well inside VMware virtual mach

[Xen-devel] Nested Virtualization Support Host-Only Hypervisors

2017-06-09 Thread Kangjie Xi
Xen supports Nested Virtualization(https://wiki.xenproject.org/wiki/Nested_Virtualization_in_Xen), which means I can run Xen or KVM hypervisor inside a virtual machine, and then create a L2 guest. However when I run a Host-Only Hypervisor (no L2 guests, like MoRE, SimpleVisor and HyperPlatform) ins
