similar to: performance overhead with backing chains?

Hi, I'm on a Dell VEP 1405 running Debian 9.11 and I'm running a few tests with various interfaces given in PCI passthrough to a qemu/KVM Virtual Machine also running Debian 9.11. I noticed that only one of the four I350 network controllers can be used in PCI passthrough. The available interfaces are: *# dpdk-devbind.py --status Network devices using kernel driver

Does anyone know how these rsync transport methods compare?: 1) Rsync to remote host via an ssh tunnel to an Rsync daemon vs. 2) Rsync to remote host via ssh remote shell - Is there a performance difference in throughput or latency? - Which one has higher protocol overhead? - Does it matter if we are sending files or receiving them? - Any memory usage differences? - Security implications? Is

Compile it with llvm to a native .o or .exe file, then run 'size' on it? E.g.: llvm-gcc x.c -o a.out -Wl,-native size ./a.out -Chris > Chris Lattner <sabre

Hey, I have written a pass and wishes to measure its performance overhead after running it over a program.I also wish to measure the size of code segment once the program is in native code.What are the easy ways in llvm to achieve this?Are there any tools available in llvm for the same ?What exactly is this llvm-prof ? Thanks a lot , Tanu --------------------------------- Do you Yahoo!?

Hi, For backing chain that all images are iscsi network disk type , such as iscsi://ip/iqn../0(base image) <-iscsi://ip/iqn../1(active image). Currently, 'qemu-img info --backing-chain' command can display correct backing file info, but after starting guest with the active image in backing chain, it don't include the related <backingStore> element in dumpxml. So,

Thanks for the reply :-) I am actually looking for ways to determine "size" of code segment when the program is in native code. Any suggestions to do that ?

Hi, I am a libvirt qe, I am testing the function about the new location of disk auth element (as sub-element of the source element) in Backing Chain Management. And I have a questions: When all the backing chain are iscsi network disk type(no matter if the authentication is exist), start the guest , it will only has the top level disk in xml and there are no other backingStore in it. The test

Hi Kynn, Thanks for expanding. I wrote a function like yours when I first started using R. It's basically the same up to your "new.env()" line, I don't do anything with environmentns. I just called my function "mysource" and it's essentially a "source with path". That allows me to find code I reuse in standard locations. I don't know why R does not

Spot on! The script qemu-ifup was indeed the cause of the problem. It's a dummy script that only does "exit 0" and it was apparently needed in the past with old versions of libvirt. I see examples on the net where it is used to configure interfaces with shell commands. I don't need it. I see that everything works fine without the <script

Hi, My goal is to assign PCI addresses to a number of devices (network interfaces, disks and PCI devices in PCI-passthrough) without delegating to libvirt the generation of those values. This should give me more control and for sure more predictability over the hardware configuration of a virtual machine and consequently the name of the interfaces in it. I'm using libvirt 4.3.0 to create

Thank you all for your comments and suggestions. @Frederik, my reason for mucking with environments is that I want to minimize the number of names that import adds to my current environment. For instance, if module foo defines a function bar, I want my client code to look like this: import("foo") foo$bar(1,2,3) rather than import("foo") bar(1,2,3) (Just a personal

Dear Tobias and all LLVM/Polly developers, Thank you very much for all your help and advice. I have submitted my proposal to GSoC 2013 application system: http://www.google-melange.com/gsoc/proposal/review/google/gsoc2013/star/1. Some tables and paragraphs are simplified to make it more readable on GSoC official pages. Any suggestion or comment would be appreciated. At 2013-05-03

Correct - qemu doesn't provide full functionality for merging in all directions. And even though upstream qemu has been adding more pieces (for example, they recently added
