I was playing around with btrfs, and did a mkfs.btrfs on one of my partition. Mistakes, it was my data partition (ext3 based). I have not yet mounted the device, but the mkfs.btrfs continued to completion. Is it possible to salvage my ext3 filesystem? Anyway to reverse the effect of mkfs.btrfs? Thank you for your help/answer. -- Regards, Peter Teoh

Hi My goal is that given a binary and the corresponding input. I want to know what IR level basic blocks are covered. I need the detail information, which is the set of all the covered BBs rather than just a number. I want to know whether there are some tools that can support this requirements. If not, I think maybe instrumentation can helps. However, I do not know too much about this. Any

Hi, I'm trying to do a Debug build for the 1st time and I keep getting this assertion: llvm-tblgen: CodeGenDAGPatterns.cpp:64: llvm::EEVT::TypeSet::TypeSet(llvm::ArrayRef<llvm::MVT::SimpleValueType>): Assertion `!VTList.empty() && "empty list?"' failed. I do not know what list this assertion is referring to. Does anyone know? I always did Release builds before

Hi All, I am trying to read group descriptor from disk. I am able to read the superblock structure successfully. But I am not getting successful to get the group descriptor. Here is my code.

Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services

Given that dom0 is itself doesn''t managed the memory directly that you only need to compile HIGHMEM4G into the dom0 or domU kernels if you intend to use more than 1G in one domX instances. ie. Even if you have more than 1Gb of total physical memory, if none of the domX use more than 1Gb of memory, there is no need to compile in HIGHMEM4G. Or, does dom0 need to be compiled with this in

Hi folks In linux kernel development, there is a debug tool called dprobe ,which can be used to dynamic insert the probes into the function of kernel source code and find what''s goning on.There is also a tool called systemtap which is based on dprobe and kernel debug info. Using the kprobes infrastructure, SystemTap is being developed to dynamically instrument the kernel and user

Hello All, I've been trying to track down information on Systemtap in Centos 4.3. What I want to know is whether there are any additions to the Systemtap functionality in 4.2 in the 4.3 release. thanks, Rich Johnson -- Richard Johnson <richj25 at earthlink.net>

Not sure if this document will be shown to any dtrace users but here is a link if you want to comment on it http://sources.redhat.com/systemtap/wiki/SystemtapDtraceComparison I have went line by line and commented on its content and in accuracies and posted it both to the systemtap email list and my blog, you can see the blogged version at

This patch causes "xm mem-set" to be lower bound on domX-min-mem option in xend-config. Another configuration option called domU-min-mem has been introduced, which works similarly to dom0-min-mem. This is prevents users from freezing the system when doing "xm mem-set" on very low values like 32M. Signed-off-by: Aravindh Puthiyaparambil

Please review. This patch fixes a few problems: a. In handle_input(), which is called from main() in xenstored_core.c, the conn->in is freed when there is no error, but conn is freed when there is error. This is inconsistent. Moreover, the conn is freed again upon exit from handle_input(), inside the main. b. Another problem is that perms_to_strings() returned a allocated memory (via

I want to use systemtap on a 5.3 system but cannot find supporting kernel-PAE-debuginfo or kernel-debuginfo-common packages.

Sorry for my ignorance but....I''ve installed a debian lenny dom0 with a xen kernel, then I''ve configured two domX. I''ve noticed that there isn''t a kernel installed for these ones. I run aptitude to update packages, I''ve updatede the dom0 kernel but....the others? _______________________________________________ Xen-users mailing list

Hi, I''ve a working xen 3.0.2 booting a gentoo linux on Dom0. I have setup a Windows XP in a DomU OK with no problems except the network!! My problem is that I wanted to give a working network interface on the DomU and the best I could. making the windows detect an network adapter, was putting: vif = [''type=ioemu''] I also tryied: vif = [''type=ioemu,

Hello, we''re using several test- and development-servers as virtual Xen-machines running on one host. Unfortunately our main application needs much memory. Its not a problem at a first view, because usually only very few instances are running at the same time. But if I understand Xen correctly, its only possible to distribute the physical memory of the machine, not the whole
