I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

After hours of googling and not really finding a definitive solution to my problem, I''m a little stuck and would really appreciate some help from others. I have a CentOS 5.4 x86-64 server running Xen 3.3 from the gitco repos as dom0. On this I have created two logical volumes comprising 8GB for the system disk (xvda) and 1.5GB for swap (xvdb). I ran mkfs.ext3 and mkswap on these to

Hi All, Hope I''m not too annoying yet.. I have CentOS 5.4 running as Domain 0. I can create CentOS guest domains via network using virt-install. However that''s a bit slow, and I don''t want to repeat the download process again if I create new guest domains. So my questions: - Can I create guest CentOS domains using virt-install and specify a dvd iso image as its

If a DomU was compramised, could the Dom0 or other DomUs be compramised? I guess I''m trying to work out how much isolated Xen gives.. Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I have just run into the following error when trying to create a debian lenny vm in XCP 0.5.0 from the command line. This used to work in 0.1.1 as far as I can remember. Here is what I did: [root@xcp1 ~]# UUID=`xe vm-install template="Debian Lenny 5.0 (32-bit)" new-name-label=lenny-test-1` VIF=`xe vif-create network-uuid=0c94af8b-da04-5417-cdd6-f4c6236aea8b vm-uuid=$UUID device=0` xe

I''m not a windows person, so I am hoping someone can help me with this... I''ve just installed a Windows 2003 Server VM and I would like to make sure that the average disk IO wait is acceptable. In Linux and other *nixes I would normally use sar or iostat for this. I have found perfmon in windows. Will this give me the numbers I need? Thanks, Matt.

Hi All, I''m new to Xen and... Happy New Year! After restarting dom-0, my dom-u prints this in console once every second, [55082.616234] __ratelimit: 1503 messages suppressed [55082.616234] clocksource/0: Time went backwards: ret=380ab26c53a I resolved this by following the instructions in "http://wiki.debian.org/Xen", which is basically changing clocksource to

I am planning to schedule a monthly XCP meeting for the community and am struggling with when to host the call. As we are a global community, there is no single optimal time to host the meeting. In an effort to support the most likely attendees, please send me your time zone if you plan to participate in these calls. I will track the most common time zones in an effort to maximize attendance. All

I have a test server with XCP 0.1.1 installed (one node, local storage) and I am having problems getting it to install debian Lenny. The host is up, DNS is working and all of the ping tests pass in the management interface. I followed the vm install guide and did the following from a prompt on the box itself: UUID=`xe vm-install template="Debian Lenny 5.0" new-name-label=lenny1` xe

For those who may be interested, the Highly Available Storage (HAST) project has recently been committed to HEAD in FreeBSD. Obviously, it is still early release and potentially not suitable for a production environment, but may be of interest to those like myself who are on the lookout for a flexible and available network storage option for Xen.

Perhaps slightly OT, but I am trying to speed up a backup script which takes an lv snapshot and does this: dd if=lv_snapshot | gzip -c > /destination/lv_file_name.gz Does anyone have an equivalent example using partimage-ng that they would be kind enough to share? - I have been told it would be much faster/more efficient, hence the question. Ten minutes of browsing the partimage-ng docs have
