Package: xen-utils-4.1 Version: 4.1.4-3+deb7u1 Severity: important When starting (or migrating in) a domain, sometimes I get the following exception: [2014-04-01 10:58:08 4821] ERROR (XendDomainInfo:2927) XendDomainInfo.initDomain: exception occurred Traceback (most recent call last): File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/XendDomainInfo.py", line 2914, in _initDomain

Dear All, I have a problem with my VPS machine ...I used Centos OS and xen application : - I created domU called vps1 with this configuration : # more /etc/xen/vps1 kernel = "/usr/lib/xen/boot/hvmloader" builder = ''hvm'' memory = 1536 name = "vps1" vif = [ ''bridge=xenbr0,ip=202.162.218.236,mac=00:16:3E:12:18:36'' ] disk = [

Hi, When Ubuntu12.04 64bit domU boot up, Intel VGA-passthrough doesn''t work. I used the command "xm create" to boot up Dom-U. Windows7-64bit-SP1 works quite well with same configuration. Boot log is as follows. Dom-U dmesg: [ 1.421858] initcall rfcomm_init+0x0/0xf1 [rfcomm] returned 0 after 2192 usecs [ 1.423021] calling i915_init+0x0/0x8d [i915] @ 387 [ 1.423023]

I assume this is an FAQ, but i couldn''t find hardly any explainations, can someone point me at the right documentation or provide an answer please. How do xm mem-set and xm mem-max work? How are they related to the memory used in the conf file for xm create. [ ie is that mem-max. ] Can you increase a domU''s memory? I have an 8G machine, and I wanted to increase one domU

Hi. We are running xen-3.0-testing. We use loop back mounted file systems. The server we are running restarts itself/crashes. This seems to happen around setting up loop back devices. (>63 loop back devices seems to trigger a crash, but we have seen then with fewer devices mounted as well). We have swapped all hardware (bar the disks) to a new server. Same issue. I see no disk

Hi Users & developers I am new to XENSERVER 5.6 and i have installed Dom 0 successfully . 1) I am requesting for help on the installation procedure of a Dom u VM with xen supported slackware linux 13, using the xe commands 2) In xenserver 5.6 i am not able to find the xend management tools (xm), it instead uses xe . Do i have to install the management tools (xm)? Thanx Moses

Hi I ve installed xen-3.2.3-0xs in Red Hat Enterprise Linux Server release 5.. & I ve successfully created guest domain with Fedora 4 image file While booting the guest domain first it shows the b---- state in xm list command and when the dom U gets booted up it turns to blank state.. Is there anything else to be configured to solve this issue?? [root@xencluster ~]# xm list Name

At least from the ''xm'' commands'' interface, it looks like domU''s just disappear after an ''xm destroy'', which I''ve been using to cut turn off the virtual power switches of domU''s. Is this by design? I''m trying to think of a good way to identify a domU throughout its lifecycle, which for me goes all the way from

I''ve seen some people asking why exposing xenstore attributes via sysfs could be useful. Here''s why I would really like to see such a patch make it into Xen: I''ve been working on getting domU''s to know enough about themselves to be manageable. I require a 128-bit UUID for each domU, and I require that each domU be able to determine its own UUID in userspace.

Hello, on a v20z, we have as DOM 0 a Solaris XEN on snv44 64bits and we have as DOM U a Solaris XEN on snv44 64 bits. We then install a pseudo driver in the Solaris DOM 1 XEN snv44: installation is ok and driver works as expected. But on reboot of DOM 1, the driver is no more there (in modinfo, driver not found). Is there something special to do after a pseudo driver installation in a Solaris

Hi, I encountered a problem while porting Solaris as a guest OS on Xen. The problem I found is that when frontend vbd driver get unloaded, it will close the vbd interface by changing the state to XenbusStateClosed. This appears to cause the dom0 hotplug scripts to remove the vbd entry from xenstore for the domU guest, preventing the vbd from being re-attached. So, my questions are: + This

Hi All , I am using xen 3.2.0 which i have built form source ,I could initially boot Dom 0 and some DomUs. But today when i tried to boot a DomU with birdge enabled it didnt work giving an error ....

I have followed the nat advice from this guide: http://wiki.kartbuilding.net/index.php/Xen_Networking#Routed_Networking_with_NAT_2 I have googled internet for weeks and read almost every thread in this forum without getting a working NAT on my system. My main question is how exactly will the iptable rules with MASQUERADE or POSTROUTING look like if you want access to the internet from Dom U ,

Hey all, I''m trying to figure out how to re-size physical partitions in the Dom U. I''ve read up what I can find on line and finally decided to have Logical Volumes in the Dom 0 and pass them as physical volumes for use in the Dom U. Here''s an example of what I''m doing. To start in the Dom 0 I created the LV''s with lvcreate -n guest_boot -L 100M
