It's particularly nasty when you have a clustered filesystem in the host. I think it would do more harm than good to have a feature like that was supposed to provide a safe-guard but then frequently didn't work. ^^ Are you trying to say that any kind of significant portion of QEMU users have clustered file-systems? I think that's unlikely, and it'd be nice if QEMU by default did a fcntl() on writeable image files to lock itself from multiple access, that'd benefit the vast majority of users.

Of course. Though, I said 'writeable' - so you might not need to use such an option.. ;) regards, -- Paul Jakma [EMAIL PROTECTED] [EMAIL PROTECTED] Key ID: 64A2FF6A Fortune: This report is filled with omissions.

Yeah, seems to be for the NIC. I also get this warning from time to time. Sometimes the reason is that clock is stalled, sometimes it has skipped. Ditto. It seems to be a harmless warning, though. Try to boot with the kernel debugger enabled, so that you can read the panic message (I guess it reboots because of a panic). D'oh, I should have known that ;). It's not able to mount root.

Re: [Qemu-devel] PATCH: floppy controller missing in acpi tables
On Tue, 16 May 2006, Ben Taylor wrote: This patch was created by Juergen Kiel, so to be clear I did not make this patch. I did however, test it, with the current CVS code, and this patch to the ACPI tables does allow a floppy drive to be seen by a Solaris 10/X86 guest. Prior to this time, changes in Solaris 10 do not correctly enumerate the ISA bus for the floppy, and therefore you could never add an Install Time Update (ITU), such as the DiskUpdate on tools.de/solaris/itu/DU.zip which has a modifed RTL8029 driver that works with Qemu on SolarisX86. Note: the file hw/acpi-dsdt.hex must be rebuilt using Intel's iasl ACPI compiler. In the hw directory, run iasl -tc acpi-dsdt.dsl. That should build the acpi-dsdt.hex file from acpi-dsdt.dsl.

Obviosly, if you boot a Solaris 10/x86 install with -B acpi-user-options=0x0, you will not see the floppy. (I see that a patch is in the works for OpenSolaris, so eventually this will be fixed for good on Solaris). Excellent, thanks Ben and Juergen. FWIW, the RTL8139 NIC in current Qemu /ought/ to work with the 'rtls' driver included with Solaris. I havn't managed to test this yet as Qemu CVS /seems/ still to have timeout issues with Solaris NV 39 (booting from the install CD at least). Also, there was an AMD PCNet patch for Qemu (by Anthony Curtis). Which (possibly) Xen are using, but it is not included with Qemu. Solaris has a driver for this, based on the newer 'GLDv2' NIC driver framework. I tried quickly (ie i spent 5 minutes on it) porting Anthony's patch to the updated VLAN-client framework in Qemu, it gets recognised by the Solaris miniroot, but I must have missed something / made a mistake as Qemu crashes. regards, -- Paul Jakma [EMAIL PROTECTED] [EMAIL PROTECTED] Key ID: 64A2FF6A Fortune: Power is poison. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
