[PATCH 0 of 2] xenpaging:speed up page-in
The following two patches are about how to speed up in xenpaging when page in pages. On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds, but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash. What鈥檚 more,the dom0 is always in high I/O pressure.

event channel in xenpaging
Hi,Olaf, I have some questions about event channel in Xenpaging to ask you. 1) In xenpaging it uses Inter-Domainain Commnication (IDC) between dom0 and domU to build bidirectional connection,but I found there is only an event channel notification from xen to dom0 when page faults happens.It seems that xenpaging_resume_page()->xc_evtchn_notify() doesn''t make any difference.So why

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
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

I have recently upgraded to Ubuntu Gutsy and, for the first time, am using a 64-bit installation.

Just an interesting data point
SO, my full load on my core UPS is two Dell R610s, one Sun X4540, one HP DL360p gen8, two six-core Thuban-II workstations plua their monitors, and the network stack and KVM. The APC SU3000RM (3KVA) that blew up last week considered this to be just short of 60% load. The new Cyberpower PR3000 (also 3KVA), wqhich operates at a 90% power factor, considers this same load to be 43% load. I wasn't
