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

I was extending the virt plugin. It already collects similar data (about VMs) using Libvirt's API, but lacks disk usage information. I went through some hoops to link libguestfs correctly to collectd. Is it okay to just include fork(), waitpid() example? It does reproduce the issue.

Apparently it is possible to run Civilization 3 under wine, but i'm having no luck. It installed fine, but won't run. With recent CVS winex i get: [~/.wine/c_drive/civ3]$ wine Civilization3.exe fixme:module:CreateProcessA (E:\~ef7194.tmp,...): CREATE_NEW_CONSOLE ignored fixme:module:CreateProcessA (E:\~ef7194.tmp,...): NORMAL_PRIORITY_CLASS ignored err:int:INSTR_IDT_Emulate Evil attempt

A quick survey... what''s the best gui debugging tool for Rails 1.0 on Linux that you''ve used? SW versions? Personally I''ve tried FreeRIDE 0.95 and RDT 0.7.0 in Eclipse 3.1.2. Both are very slow and the latter got quite a few bugs itself. TIA! -- Posted via http://www.ruby-forum.com/.

When writing to a RHEV target, virt-v2v launches the libguestfs appliance with euid:egid = 36:36, which is required to write to an NFS target using root_squash. Since the update to use an febootstrap cached appliance, this causes an error on startup as the cached files are owned by root, but the cache directory is owned by 36:36. The reason for this is that execve() resets euid and egid to uid and

Can I get people from other platforms to test the waitpid.patch to see if it solves hang-on-exit on their platform? I can confirm Solaris at this moment (but I've not done heavy testing at this moment) that is works like a charm (Solaris 7). It handles 'sleep 90&' vs 'nohup sleep 90&' correctly (killed, vs left). thanks. - Ben ---------- Forwarded message

Hi, thank you very much for reporting this!

All other plugins are forbidden to fork(), popen() or

As Eric Blake noted in: https://www.redhat.com/archives/libguestfs/2016-April/msg00154.html libguestfs doesn't correctly handle the case where waitpid receives a SIGCHLD signal and the main program has registered a non-restartable signal handler. In this case waitpid would return -EINTR and we would print an error, but actually we should retry this case. This adds two new internal functions,

To Whom It May Concern: Below is a patch, that I have used to eliminate the unexplained errors in the rsync program. I was able to trace the problem to the order in which the sigchld_handler and wait_process routines were executed. If sigchld_handler executes first it retrieves the status that wait_process needs to indicate proper rsync termination. The code below allows the sigchld_handler to

I noticed that the MySQL root was the user accessing the MYSQL Server and that there was no password used. Due to security concerns I have added a password to the root user but this has now broken my Rails applications. I believe I have found the config file but am unsure how to edit it. Do I

Thank you, Rich, This was the issue indeed. export LIBGUESTFS_BACKEND=direct fixed it. The next step I tried was to integrate libguestfs in collectd virt plugin to collect this data automatically. In this case I'm having an unknown error in add_libvirt_dom() (same with add_domain) when it's invoking qemu-img to create overlay image. There is no difference between manual and service
