Not sure if this is the right place to come to, but I don't have "RHN" support.....I'm hoping someone can help me out here. I have downloaded the RHEL .ios file and burned it to DVD/CD, my laptop is primed to Boot From CD/ROM Drive, I start the installation using the semi-graphical interface, and the first few options are a breeze, then it gets to identifying the CD drive

Hello, I have a CentOS VM with only one disk on a Xenserver. The disk has 2 partitions: /dev/xvda1 -> /boot /dev/xvda2 -> a physical volume for LVM I added 5GB to this disk via Xencenter to extend /dev/xvda2. Usually I just have to do "pvresize /dev/xvda" to have the additional space added to the disk. But for some reason it does not work for this disk. [root ~]# pvresize

Hi, I looked at the sources and figured out all about the P2M, M2P tables and mappings, Now I''m trying to figure out how dom0 virtual memory is implemented, and I have some questions. The platform I''m working on is x86 with Intel VT enabled. 1. Is dom0 virtual memory managed differently than the other domains? what about hvms? and domUs? 2. What tables are used to manage the

Hey all, I've found a bug in either the PBQP register allocator or in VirtRegRewriter. I'm observing this assertion in VirtRegRewriter::rewrite() fail: unsigned VirtReg = MO.getReg(); unsigned PhysReg = VRM->getPhys(VirtReg); ... assert(!MRI->isReserved(PhysReg) && "Reserved register assignment"); Indeed there is a case where

Hi every one, I am trying to load a custom kernel with Syslinux on special purpose pc. Surprisingly Syslinux-4.06 boots my kernel, initrd and finally the OS perfectly from an SD-Card. The problem arises when I use the Syslinux-6.03 where the syslinux hangs right at the beginning After I see the message 'Loading vmLinuz0 ...' I read a few posts on your forums and figured out it has to do

I want to full understand register coalescing and how to coalesce copies. From what I have seen from "SimpleRegisterCoalescing," "RegAllocLinearSpan," and "RegAllocPBQP" there are three indicators for the copy instruction x = copy y. Assume that the value number of x does not equal the value number of y. For "x = copy y", let the boolean values a,b, and c,

Hi, I got this NOTE on most of the link. But I am not getting reason for this. Why someone should not add physical NIC to virbr0. I tried to add my eth1 to virbr0 and it get added. So whether it affects to some functionality of NAT network? -- Sagar Dilip Shedge, Pune. With Regards.

Hello List, We’re currently managing VMs across approximately 26 physical hosts. We tend to migrate VMs around a lot to do things like spread load and keep VMs running when physical hosts are in need of package updates. Suffice it to say sometimes finding out which physical host a VM is currently running on can be a pain. Anyone know of an open source tool that will give me a snapshot of

RFC: Generalize means the sanitizers work with memory Overview ======== Currently, LLVM sanitizers, such as Asan and Tsan, are tied to a specific memory model that relies on presence of hardware support for virtual memory. This prevents sanitizers from being used on platforms that lack such support, but otherwise are capable of running sanitized programs. Our research indicates that adding

Dear all, When I compared the performance of some application on both a Xen domU and a standard linux machine (where domU runs on a similar physical mahine), I notice the application runs faster on the domU than on the physical machine. Instrumenting the application code shows the application spends more time on popen() calls on domU than on the physical machine. I wonder if xenlinux does some

...&CLP::FPUaOffsetClassRegClass, TRI); The code after customInserter seems valid but the compilation later hang-up in an infinite loop in procedure computeVirtRegs(); of pass LiveIntervals::runOnMachineFunction. In other targets, I've seen an example with a setIsDef(true) for such physically mapped register. Is there something missing in my code (register other setting,...) ?

Hi, Roman, maybe I can try to answer this. I think that all boils down to having register to reload spilled values. Once a register is spilled, its live range is split into smaller pieces. These pieces most be contained into registers, and it is the task of the allocator to find these registers. Imagine that you have something like: Before After allocation: allocation: a

I accidentally realized today that any domU''s using the paravirt disk driver potentially suffer from poor performance when they get handed in a physical volume and partitioning is done inside the guest. The physical volume passed in has to be one that has the compat 512 logical sector size but hints its real sector size (eg. 4096) as physical sector size. In dom0 handling is correct and
