Parametric survival models with left truncated, right censored data
Dear All, I would like to fit some parametric survival models using left truncated, right censored data in R. However I am having problems finding a function to fit parametric survival models which can handle left truncated data. I have tested both the survreg function in package survival: fit1 <- survreg(Surv(start, stop, status) ~ X + Y + Z, data=data1) and the psm function in package

One question on MMIO
In sh_page_fault(), there are some code like following, why we think it is mmio only when paging_vcpu_mode_translate(v)? Thanks Yunhong Jiang /* What mfn is the guest trying to access? */ gfn = guest_l1e_get_gfn(gw.eff_l1e); gmfn = vcpu_gfn_to_mfn(v, gfn); mmio = (is_hvm_domain(d) && paging_vcpu_mode_translate(v) &&

[PATCH] unshadow the page table page which are used as data page
The patch deals with the situation which guest OS uses unused page table pages as data pages and write data to them. The pages will still be grabbed by Xen as page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page. The patch

Page tables in Xen
Hi, I have a question about memory page tables in Xen. As far as I understood, every modification to page table will go through Xen(hypervisor). Is it so that all page tables are actually allocated in Xen(hypervisor) instead of guest OS(domain)? Also, is it the case that Xen(hypervisor) needs to maintain a page table for each process running in every domain? Thanks Haifeng

heads-up: PV and HVM save routines in libxc have merged
...into a single xc_domain_save() function. I''ve tried to DTRT with the IA64 version.
