True, kvm has enough crash-bugs elsewhere that I already have to deal with that. It'd be nice to distinguish kvm/qemu bugs from guest bugs, though :-) kvm/qemu also has lock-up bugs, where it's spinning at 100% and the guest seems to be stuck (even though the VNC server continues to work). That's a bit harder to fix with a wrapper script. -- Jamie From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from mailman by lists.gnu.org with tmda-scanned (Exim 4.43) id 1N52kQ-0005eC-5Q for qemu-devel@nongnu.org; Mon, 02 Nov 2009 14:39:26 -0500 Received: from exim by lists.gnu.org with spam-scanned (Exim 4.43) id 1N52kL-0005cv-OZ for qemu-devel@nongnu.org; Mon, 02 Nov 2009 14:39:25 -0500 Received: from [199.232.76.173] (port=43386 helo=monty-python.gnu.org) by lists.gnu.org with esmtp (Exim 4.43) id 1N52kL-0005cs-Hk for qemu-devel@nongnu.org; Mon, 02 Nov 2009 14:39:21 -0500 Received: from mail2.shareable.org ([80.68.89.115]:42700) by monty-python.gnu.org with esmtps (TLS-1.0:RSA_AES_256_CBC_SHA1:32) (Exim 4.60) (envelope-from ) id 1N52kL-0000y9-6s for qemu-devel@nongnu.org; Mon, 02 Nov 2009 14:39:21 -0500 Date: Mon, 2 Nov 2009 19:39:08 +0000 From: Jamie Lokier Subject: Re: [Qemu-devel] Re: [PATCH] whitelist host virtio networking features [was Re: qemu-kvm-0.11 regression, crashes on older ...] Message-ID: <20091102193908.GB15212@shareable.org> References: <4AE9A299.5060003@codemonkey.ws> <1256826351.10825.69.camel@blaa> <4AE9A90F.1060108@codemonkey.ws> <1256827719.10825.75.camel@blaa> <1256830455.25064.155.camel@x200> <1257172722.5075.7.camel@blaa> <4AEEFDCE.1000006@codemonkey.ws> <20091102155228.GB9655@shareable.org> <4AEF22D5.3040702@msgid.tls.msk.ru> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <4AEF22D5.3040702@msgid.tls.msk.ru> List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Michael Tokarev Cc: Mark McLoughlin , Scott Tsai , kvm , Dustin Kirkland , Rusty Russell , qemu-devel , jdstrand@canonical.com, Marc Deslauriers , kees.cook@canonical.com Michael Tokarev wrote: > If you want kvm to behave like this, wrap it into a trivial > shell script that restarts the guest.
