Mem_event API and MEM_EVENT_REASON_SINGLESTEP
Hello, I''m interested in using the mem_event API (or it''s LibVMI wrapper), but I''m interested in capturing write events anywhere in a domU guest''s memory, _and_ not just once for each page write, but every time a page is being written to. To this end, I''ve looked at the xen-access.c example, where at first all the pages are being monitored:

[PATCH V4] mem_event: Add support for MEM_EVENT_REASON_MSR
Add the new MEM_EVENT_REASON_MSR event type. Works similarly to the other register events, except event.gla always contains the MSR address (in addition to event.gfn, which holds the value). MEM_EVENT_REASON_MSR does not honour the HVMPME_onchangeonly bit, as doing so would complicate the hvm_msr_write_intercept() switch-based handling of writes for different MSR addresses, with little added

Side by Side Barplot Newbie Question
Hi, Many apologies for sending this twice. I accidentally hit the send button before I finished writing my mail. I am new to R and I hope someone can help me with my problem. I am trying to draw a side by side barplot. There is a main experiment and there are many sub experiments within the main experiment. I would like to draw a bar plot showing the number and type of sub_experiments done for

Fitting ELISA measurements "unknowns" to 4 parameter logistic model
Hello, I am trying to fit my Elisa results (absorbance readings) to a standard curve. To create the standard curve model, I performed a 4-parameter logistic fit using the 'drc' package (ExpectedConc~Absorbance). This gave me the following: > FourP A 'drc' model. Call: drm(formula = Response ~ Expected, data = SC, fct = LL.4()) Coefficients: b:(Intercept) c:(Intercept)

using @releaseDomain to subscribe for domain destruction
Hello!. How can i use @releaseDomain from dom0 to subscribe for domain destruction? I''m try to add watch for @releaseDomain path with token equal of needed domain id. But when another domain dies, i get domain that i provide via token to xs_watch. Is that possible to get id of domain what released from xenstore? -- Vasiliy Tolstov, Clodo.ru e-mail: v.tolstov@selfip.ru jabber:

Hypervisor to dom0 communication
Hello, I''m interested in establishing a communication channel between the Xen hypervisor and a dom0 userspace application. Ideally this would be a 2-way channel, with the hypervisor asynchronously notifying this application, and then (for certain types of messages) wait for a reply from the userspace consumer. To this end, I''ve been reading xen-devel posts [1], read the

Seemingly Unrelated Negative Binomial (SUNB) estimation
Dear all, I am trying to estimate a system of equations with a Seemingly Unrelated Regression. However because of the characteristics of the data I'd like to do it with a negative binomial estimation. Would anybody know how to implement a Seemingly Unrelated Negative Binomial (SUNB) estimation in R? Thank you in advance for your help. Best regards, Elisa Lanzi -- Elisa Lanzi PhD student in

Amelia imputation - column grouping
Hi everybody, I am quite new to data imputation, but I would like to use the R package ' Amelia II: A Program for Missing Data '. However, its unclear to me how the input for amelia should look like: I have a data frame consisting of numerous coulmns, which represent different experimental conditions, whereby each column has 3 replicates. I want amelia to perform an imputation across

creating standard curves for ELISA analysis
Hello R guru's I am a newbie to R, In my research work I usually generate a lot of ELISA data in form of absorbance values. I ususally use Excel to calculate the concentrations of unknown, but it is too tedious and manual especially when I have 100's of files to process.

splitting matrices
Dear useRs, i want to split a matrix having 1116rows and 12 columns. i want to split that matrix into 36 small matrices each having 12 columns and 31 rows. The big matrix should be splitted row wise. which means that the first small matrix should copy values which are in first 31 rows and 12 columns of the big matrix. similarly 2nd small matrix should contain values from 32nd to 63rd row of the
