Hello, I build and installed Xen (4.1.3) from source, and I think I have got it working. Well, almost. I am using unmodified kernel of Fedora16 as my dom0 kernel. So this is what happened. I am able to boot into Xen, but the "xl info" failed with the standard error message mentioned in the tutorial. "libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to

As any other daemon, I''d assume it should be possible to restart xenstored (i.e. if it crashed or if, during development, a fix was made to it that needs to be tested). However, as I learned after over a day of digging, things don''t work anymore after doing so: Since the watches are transient, they''re lost with the daemon going away. Right now I specifically need this in

I just downloaded Xen-4.1.1 from xen.org, compiled it, and installed it. I then compiled kernel 3.0.0 and added the hypervisor and dom0 kernel in a grub 2 entry. After booting, I executed "xl list," to confirm the hypervisor was running. I was greeted with this message: libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to stat /var/run/xenstored.pid: No such

By default, /var/lib/xenstored is mounted tmpfs in centos 5 but this doesn't appear to be true for Xen4CentOS. This can cause performance issues as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=446089 I'm not sure if this should be part of xencommons, but if not, adding a tmpfs mount should probably be documented on the quick start wiki page. Thanks, Sarah

YaST2 sysconfig can logically group the various sysconfig settings if the files are tagged. Add the missing (YaST specific) tags to xencommons.

Dear all, I followed the steps described in the wiki in order to get an Arnadle board running Xen, but I''m having trouble in starting a domU. Let me describe you the steps I followed. Sorry for such a long mail, but I think that a verbose description is necessary so you can point me what I''m doing wrong. I couldn''t boot properly over the network. This is why I

Hello, I am running a mail benchmark test using smtp-source[1] with VM running postfix on Xen hypervisor.

The contents are the wip.testme branch currently on salsa. I combined the wip.initscript and wip.oxenstored into this and added more things today. I think this is pretty gtg and it's smoke tested (in several cases by scping files around instead of doing package build), so it needs a final extra review and test round before putting it in master branch (which I don't want to force push). I

Hello, I noticed a strace delay when running "virsh list" on my Xen-4.1.3 test server. On further investigation I noticed that in XenStore there were multiple /vm/$UUID entries suffixed by -$VERSION, especially I hat 16 entries for my dom0. For each reboot of the host I get a new entry. After disabling Xend I get the following output after a reboot: > root at xen5:~# xenstore-ls

Currently PVHVM Linux guests after ddacf5ef684a "xen/pv-on-hvm kexec: add xs_reset_watches to shutdown watches from old kernel" hang when run against oxenstored because it does not handle the unknown XS_RESET_WATCHES operation and does not reply. The symptom of this issue is a hang during boot at this point: cpu 1 spinlock event irq 70 CPU 1 irqstacks, hard=dec94000

Hi Jan Back before 4.3 release you complaint about the hardcoded modprobe for blktap / blktap2 in xencommons script. I started to look into it this week and tried to do this modprobe automatically in libxl (that''s the idea we discussed before 4.3 IIRC). Unfortunately I didn''t manage to find any canonical documents on how a user space process can trigger a modprobe.

And how should the init script deal with that? If they specify an absolute path, it should be used. Eg, /home/alice/Xen/xen/tools/xenstore/xenstore If the user specifies /bin/bash

Hi everyone, I''m trying to start up domU on xen for ARM (Cortex-A15 Fast models). I follow the instructions to build xen-tools with this link: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling. But there seems to be something wrong when I start up domU. First, I get errors in create domU with xl: root@(none):/home/xiaogw# xl create domU-config xc: error:

The following series improves kexec in a Xen PVonHVM guest.

The command removes all watches and transactions for the guest. The following patches make use of the new command to wipe all existing
