Any thoughts on setting breakpoints around hypercalls? ---------- Forwarded message ---------- From: Kip Macy <kip.macy@gmail.com> Date: Dec 26, 2005 12:14 AM Subject: setting breakpoints around hypercalls in a domU causes dom0 to lockup To: xen-devel <xen-devel@lists.xensource.com>, Keir Fraser < Keir.Fraser@cl.cam.ac.uk> Stepping through hypercalls (at the source level, not

I''ve locked up my dom0 a couple of times this morning copying a 3GB file from local disk to an NFS mount(neither xend nor guests running). I don''t encounter this problem on the stock CentOS 4 kernel. The machine is a PowerEdge 2850 with 2 e1000 cards - the one in use is connected to a PowerConnect 2216 10/100 switch and has negotiated 100Mbit. I''ll check if the stock

Please CC as I''m not subscribed to valgrind-developers. Under Xen the toolstack is responsible for managing the domains in the system, e.g. creating, destroying, and otherwise manipulating them. To do this it uses a number of ioctls on the /proc/xen/privcmd device. Most of these (the MMAPBATCH ones) simply set things up such that a subsequenct mmap call will map the desired guest

Hello, I''m trying to get PDB working in accordance with the instructions at http://www.cl.cam.ac.uk/~sos22/replay.bk/docs/misc/XenDebugger-HOWTO and a message from this list: http://lists.xensource.com/archives/html/xen-devel/2004-08/msg00017.html When I try to build pdb I first get errors because the Makefile is configured to treat warnings as errors, and there are some warnings.

It looks like I can no longer map a page as uncacheable. Is this intentional? -Kip _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Presumably as a result of recent changes, FreeBSD no longer works with writable page tables. In the short-term I''m more interested in functionality than performance. This patch disables them and fixes a compile issue. # This is a BitKeeper generated diff -Nru style patch. # # ChangeSet # 2005/04/29 19:26:00-07:00 kmacy@curly.lab.netapp.com # disable writable pagetables + compile

Just wanted to try domU freebsd and found <http://216.239.59.104/search?q=cache:M_4r1b-RG- EJ:www.fsmware.com/xenofreebsd/5.3/xenbsdsetup.txt&hl=en&lr=&strip=1> but the webservice on www.fsmware.com seems to be down/unavailable.

I encountered a problem with dom0 when rebooting and running an intel gigabit card using the pro/1000 driver. When the system tries to shut down I get the following output of an strace command : ......... 17:10:49.063616 socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 3 <0.000029> 17:10:49.063689 ioctl(3, 0x8913, 0xbffffc80) = 0 <0.000018> 17:10:49.063751 ioctl(3, 0x8914, 0xbffffc80) =

Hey guys, As I go through the console code, I notice that the domain console information is being stored in /console/%d/domain instead of within the /domain tree as one would expect. The reasoning seems obvious to me, there''s no easy way to get the UUID for a domain so constructing a UUID based path outside of Xend is very difficult. Perhaps now is a good time to reconsider just

I''m using the exact same setup as I''ve successfully been using for both -testing and -unstable. However, at least as of today, guests on -testing can''t see the network. >From my -unstable machine: vif13.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1095 errors:0 dropped:0

I'm having problems getting PF + ALTQ to work on em(4) interfaces under 8.0-RELEASE. Kernel was rebuilt with the additional options necessary for ALTQ and what not. Same basic configuration works fine under 7.2-RELEASE. Basically, the queues create successfully but running a pfctl -vsq shows a zero packet/byte count for all queues, even the interface's root queues. This same problem is

Hi! May anyone assist me with booting FreeBSD DomU (under Debian Dom0). Now I''m using the kernel-current, downloaded from Kip Macy site at http://www.fsmware.com/xenofreebsd/7.0/download/ The problem is that I can''t specify _any_ root, the kernel can recognize: Mount point / had 1 dangling refs Manual root filesystem specification: <fstype>:<device> Mount

Using the 2.0.6 demo cd image, I booted the supplied freebsd image and rsync''d the file system to an NFS server. However I don not seem to be able to succesfully boot from it the system just hangs here: xn0: bpf attached xn0: Ethernet address: aa:00:00:61:1c:d4 lo0: bpf I have modified /sbin/start_freebsd.sh and /etc/xen/freebsd.py to generate the following configuration: xendemo:~#

Is there any way for unprivileged guests to map each others memory without grant tables? Now that the pressure is off for me to support SMP internally, I''d like to switch back to using -testing.

Hi, I understand that 64-bit support for xen (from the side of host OSes) will be a little late, so i have a couple of questions: 1) Can i install a x86 32-bit xen kernel on x86_64 pc, without problems? 2)If i install a x86_64 xen kernel, can i run 32-bit host OSes on it? I know little about Xen, so i''d like to clear these out. Thanks

Question about bridge configuration on the host and virtual machine side. I am not able to correctly configure xen so that the virtual machine can access the network.

Hi, One of my lecturers is putting together an applications CD to go with RedHat 6.0 with stuff he thinks would be useful for his students. He wants to put R on it, but he's having trouble compiling R and using an RPM on RH 6.0. It appears to be either kernel or glibc related, but I don't have the time right now to figure out what the problem is (exams...). Does anyone have an RPM of R

This is a fourth cut of the hypervisor patch of the proposed XENMEM_claim_pages hypercall/subop, taking into account feedback from Jan and Keir and IanC, plus some fixes found via runtime debugging (using privcmd only) and some added comments/cleanup. [Logistical note: I will be out tomorrow (Friday) plus US holidays next week so my responsiveness to comments may be slower for awhile. --djm]

I have been using Xen on a daily basis on a production (but not critical) machine for a number of months now. It''s looking really good. One thing that I have not yet seen anyone mention as a feature that I would really like to see is the ability to overcommit memory. I have 2G of RAM in my machine. I would like to give a developer his own virtual domain to sandbox his application
