Hi All, I am trying to start a lxc container using libvirt and I am facing an issue due to pivot_root. The return code from the system call ?pivot_root? is EINVAL (Invalid arguments). I isolated the issue to this specific condition check within the system call. This is an code snippet from fs/namespace.c::pivot_root * error = -EINVAL; if (root.mnt->mnt_root != root.dentry)

Hi, Is it possible to shutdown/restart a system LXC from within the container? From what I have observed(Version - 0.8.4): * The libvirt_lxc manager process, which listens on the /dev/pts for console connection loops infinitely. Let me know If I am missing out something obvious or there exists any other way to shutdown/restart system LXC from within. Any pointers in

Hi All, I am facing the following issue, while using Libvirt version 0.8.4. (1) Libvirt API does not return, since the qemu-kvm process is hung up. Based on the information available on mail thread *https://bugzilla.redhat.com/show_bug.cgi?id=676205* (comment 26 - scenario 1), this has been fixed in later version of Libvirt, specifically in RHEL 6.2(libvirt 0.9.4). I have checked the

Hi, I hope this is the right list for initramfs questions. First I noticed: with initrd I can use real-root-device and pivot_root mechanisms. with initramfs only pivot_root works. My init (or linuxrc) scripts end like this: mount -t xfs -n -o ro /dev/mapper/root /new-root umount -n /sys || true umount -n /dev || true umount -n /proc || true cd /new-root pivot_root . initrd exec chroot .

Hello, I'm new in ext3. I installed RH7.2 with ext3. For a short time it worked properly, but when I compiled the linux kernel (2.4.9-13) from RH package, the old kernel didn't boot again (I didn't change anything with the old binary). I downloaded kernel 2.4.14 and ext3 patch for this version. After the compilation and installation I rebooted the system. I got answer something

Dear ALL, Does anyone know how to get the complete code program for any build-in function in R, e.g. when I tape mean in the R-console, I get the following:  mean function (x, ...) UseMethod("mean") <environment: namespace:base> but I need the full mean function. Thank in advance, Alphonse. [[alternative HTML version deleted]]

Hello, I have an openups2 ups. It works very well with nut, except two things: 1) It keeps sending a 'libusb_get_string: invalid argument' message to the log; 2) It does not report any command. Following http://nut-upsdev.alioth.debian.narkive.com/bmJyFFkO/libusb-get-string-invalid-argument, I was able to fix the error message using the attached patch. I do not know how ot fix the

Hi I had some doubts regarding what all the init application should do: >> so, that should that application do? >> - mount /dev/hda1 /new-root >> - cd /new-root >> - run-init 1. Of what I understand, before exitting, init should mount the realroot and execute the init process. Is realroot the '/' or the empty directory created (in the cpio archive) ?

I converted my lvm root initrd to an initramfs by putting glibc, lvm, pivot_root, my linuxrc, etc. in my initramfs source file. I use ash compiled against klibc to run my linuxrc Unfortunately - pivot_root . initrd - complains - pivot_root: Invalid argument I suspect this may be because you can't pivot_root using a cpio initramfs root? If so, what should I do instead? Should I

I'd like to increase the number of lines available via the vertical scrolling bar when running RGui.exe under win95. Would think this is set in options() or /etc/Rconsole, but haven't been able to figure out how. Note that it's output I'm concerened with viewing, not the command history. Can anyone help? Thanks!

A patch for a few more hiccups and trivialities in kinit.c: * The check_path() calls check for "/root" and "/old_root" - I believe that should be "/root" and "/root/old_root". * chdir("/") is recommended after pivot_root() * init_argv[0] isn't set properly to the basename pointed to by char *s - this fix also eliminates six lines of

Hi everybody, I had a problem which you may be interested in. I set data=writeback in /etc/fstab for each of my ext3 partitions (because it complains on "mount -o remount,data=writeback" with "ext3: journal mode can't be altered on remount" or similar) and rebooted. Problem: / was mounted read-only, I couldn't remount it (because mount appends the options from fstab,

After supermin has finished running, the initramfs files sit around occupying swappable memory but serving no further purpose. This saves a little memory, at the cost of about 1ms of extra boot time. --- init/init.c | 50 ++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 48 insertions(+), 2 deletions(-) diff --git a/init/init.c b/init/init.c index 733d66e..5ac53e9 100644 ---
