Hello there, We (a small hosting community) are running a steadily growing number of Xen domUs on a quad dualcore Xeon server with 64GB ram. We''ve got 100 running domUs at the moment. Trying to create a new one results in this error: Error: (1, ''Internal error'', ''launch_vm: SETVCPUCONTEXT failed (rc=-1)\n'') If I shut down another domain, I can

vtd: Fix for irq bind failure after PCI attaching 32 times Originally when detaching a PCI device, pirq_to_emuirq and pirq_to_irq are freed via hypercall do_physdev_op. Now in function pt_irq_destroy_bind_vtd, duplicated logic is added to free pirq_to_emuirq, but not pirq_to_irq. This causes do_physdev_op fail to free both emuirq and irq. After attaching a PCI device for 32 times, irq resources

The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature. Please review. v2: - update mem_event_check_ring arguments, check domain rather than domain_id - check ring_full first because its value was just evaluated - check if ring buffer is initialized before calling mem_access_domctl/mem_paging_domctl

This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.

Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of
