Am I right in thinking that the numbering of the versions are in synch with the gcc version that one is recommened to build with? In other words "use gcc version 3.foo". -- John Maclean - 07739 171 531 MSc (DIC) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If so, no, you can use gcc 4.y to compile Xen 3.x - as long as you don''t go 4.1 on a very old Xen release, as 4.1 has more aggressive optimization and it will break HVM functionality in several places (because this code, in older releases cheats by passing a structure as a parameter, modifying the data within the structure and expecting those changes to persist when the function returns, but the compiler being very clever figures "This is a local copy, I don''t HAVE to write things back to a local copy, I''ll skip this". So later versions of the code pass a pointer to the structure and this makes the compiler understand that it''s not just a local copy, but actually refers to some memory elsewhere in the system, and thus writes to it will have to be performed). If you weren''t asking my rephrased question, could you please rephrase the original question... ;-) -- Mats> > -- > John Maclean - 07739 171 531 > MSc (DIC) > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

As far as I know, (all | most) current Linux distributions are at gcc 4.x, and Xen builds and runs fine with them.

I ask because because a few errors from `make world`. I''ve tracked them down and it seems as if I should''ve installed X11-devel packages. Originally I thought that my version of gcc was too recent.

[Xen-users] Windows install sees only 1MB [MBR] partition.
I am trying to install Windows XP as guest to be run under HVM on its own partition -- not in an image file as described in the documentation. The critical parameter is: disk = [ ''phy:sdb6,hda,w'', ''file:/var/iso/WINDOWS_XP.ISO,hdc:cdrom,r''] My DomU works properly and boots to the installation disk. But during the installation procedure I get the XP installation partitioning screen, but my partition is only recognized to be 1MB long. The partition information box says: "1 MB Disk 0 at Id 0 on bus 0 on atapi [MBR]" So it thinks the sdb6 partition as viewed as an hda drive as a 1 MB disk. Any ideas why? Can you not install guest Windows XP into a partition or must it be in a file image?

RE: [Xen-users] Windows install sees only 1MB [MBR] partition.
It is a 15MB partition. It is not the first partition. When I try to put in 1MB to take the whole 1MB in the size prompt of that windows screen, it does not accept this figure. One think I did note is that HVM loader will not accept a virtual block device with a numbered partition "hda1" it only accepts "hda". This is okay. disk = [ ''phy:sdb6,hda,w'', ''file:/var/iso/WINDOWS_XP.ISO,hdc:cdrom,r''] This doesn''t work. disk = [ ''phy:sdb6,hda1,w'', ''file:/var/iso/WINDOWS_XP.ISO,hdc:cdrom,r''] On Fri, 2006-15-12 at 17:24 +0100, Petersson, Mats wrote:> > > -----Original Message----- > > From: xen-users-bounces@lists.xensource.com > > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Edward Ing > > Sent: 15 December 2006 16:08 > > To: Xen Users > > Subject: [Xen-users] Windows install sees only 1MB [MBR] partition. > > > > I am trying to install Windows XP as guest to be run under HVM on its > > own partition -- not in an image file as described in the > > documentation. > > The critical parameter is: > > > > disk = [ ''phy:sdb6,hda,w'', ''file:/var/iso/WINDOWS_XP.ISO,hdc:cdrom,r''] > > > > My DomU works properly and boots to the installation disk.

Re: [Xen-users] Windows install sees only 1MB [MBR] partition.
Edward, Hi, I had the same problem using an LVM partition and it turned out I needed to specify the location of the LVM volume exactly or the BIOS that boots the HVM couldn''t see it. So instead of disk = [ ''phy:sys_vg/windows_os,hda,w'' ] it had to be something like disk = [ ''phy:/dev/sys_vg/windows_os,hda,w'' ] I hope that somehow helps and isn''t totally irrelevant, Ryan.

This did the trick perfectly. Thanks. I''ll have to report it as a bug in the documentation.

Re: [Xen-users] Windows install sees only 1MB [MBR] partition.
Also, I could not get it to read the physical hard drive until I explicitly used the /dev prefix for the cdrom. disk = [ ''phy:/dev/sdb6,hda,w'', ''phy:/dev/hdc,hdc:cdrom,r''] Now I can boot to cdrom, without having to make an image.

[Xen-users] A list of which OS do/do not install from CDROM and image
Here is a list of OS which I have tried to install via the HVMloader/cdrom method. 1) FreeBSD 6.1 -- no. But you can see the boot console running into the BTX loader problem. 2) Ubuntu i386 -- no. You just get a blank console window. 3) Ubuntu amd64 -- no. You just get a blank console window. 4) Windows XP Professional -- installs beautifully. 5) Mac OS -- I have the disc -- but I will have to find that hack -- so you won''t get an answer on this one soon. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, OK, my list is a little different: > 1) FreeBSD 6.1 -- no. But you can see the boot console running into never tried any BSD > 2) Ubuntu i386 -- no. You just get a blank console window. 5.10, 6.06 and 6.10 are working as HVM and paravirt guest. > 3) Ubuntu amd64 -- no. You just get a blank console window. Never tried any x64 guests - for me it doesn''t make much sense to use x64 systems at all. With xen 3.0.1/3.0.2 and SLES 10 beta I had some trouble to get running the x64 versions at all, so I went back and used only the i386 versions! I also had success in get runnig SuSE Linux 10.0/10.1, SLES 10 beta/GM as HVM and paravirt guest and I also had success with RHEL WS4 on Xen 3.0.2. > 4) Windows XP Professional -- installs beautifully. Works for me too, W2k3 server also works but I don''t get working any IBM OS/2 or eComStation version as HVM guest :-( -- Chau y hasta luego, Thorolf _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
