Hello, I've got several machines which I'm trying to netboot, the setup is a bootserver using dhcpd3 and tftpd-hpa. When a machine boots up, it gets an ip address and downloads pxelinux.0 from the server, then it starts searching for pxelinux.cfg/[MACADDRESS] pxelinux.cfg/0A0000F0 and so on. On the server side I see in the syslog the client's DHCP-request and the client downloading

When we use this pointer, we cast away the const modifier and modify the data. I think it was an accident to declare it as const.

If m.num is too large then the "m.num * sizeof(*m.arr)" multiplication could overflow and the access_ok() check wouldn't test the right size.

Copy back of per-slot error codes is only necessary for V2. V1 does not provide an error array, so copyback will unconditionally set the global rc to EFAULT. Only copyback for V2.

Hi! There''s a include path mistake when trying to build tools/libxc on OpenBSD: gcc -O2 -fomit-frame-pointer -m32 -march=i686 -DNDEBUG -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -D__XEN_TOOLS__ -Werror -fno-strict-aliasing -I. -Wp,-MD,.xc_core.o.d -c -o xc_core.o xc_core.c In file included from xc_private.h:18, from xg_private.h:16,

I am tasked with installing xen on a FC4 machine. I went ahead and followed the fedora xen howto, however when I rebootrd into the dom0 kernel I would get a page full of hda: lost interrupt followed by a blank screen. I then decided to remove all that and go with a xen-testing from source build. Now when I do "make tools" in the -testing directory I get: [...] In file included from

Thanks. I have already previewed the xenctrl.h. The following is what I understand: libxc is compiled to a file name after 'xc**' endding with '.so', xend communicates with domain0 through xc and domain0 communicates with hypervisor through privcmd.

Hi, I''m running a recent fedora-compiled xen kernel and the libs that come with it. I''m unable to start xend. I''ve tracked down the problem to the fact that xen.lowlevel.xc seems to be unable to talk to xen via /proc/xen/ privcmd. When I run the test program below, I get a "function not implemented" which I think results from the fact that an ioctl
