Hi there, We are using latest version of XCP on 6 hosts. While issuing VM.start or VM.start_on xmlrpc functional call , it says : {''Status'': ''Failure'', ''ErrorDescription'': [''SESSION_INVALID'', ''OpaqueRef:cfb6df14-387d-40a1-cc27-d5962cba7712'']} However if I put VM.start in a loop maybe after

The memory permutation cause a slow down in case of a save/restore (bug 1143). It works better when the mixing is done with 2MB chunks.

To make use of the new node aware memop hypercall, the xc_domain_memory_populate_physmap function is extended by a node parameter. Passing XENMEM_DEFAULT_NODE mimics the current behavior.

Last year we had a discussion[1] about how the hypercall ABI unfortunately contains fields that change width between 32- and 64-bit builds. This is a huge problem as we come up on the python management stack for ppc64, since the distributions ship 32-bit python. A 32-bit python/libxc cannot currently manage a 64-bit hypervisor. I had a patch but was unable to test it, and some other things were

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its

Attached are the patches to support super page with EPT. We only support 2M size. And shadow may still work fine with 4K pages. The patches can be split into 3 parts. Apply order is as attached. tool.diff To allocate 2M physical contiguous memory in guest except the first 2M and the last 2M. The first 2M covers special memory, and Xen use the last few pages in guest memory to do special
