initscripts, xen and bonding
by Axel Thimm 04 Mar '07

04 Mar '07

Hi, I'm having a hard time getting bonding to work on FC5t3. It looks like the bond0 interface bond0 is renamed to pbond0 by xen [*] and the enslaving does not work anymore then. It works if I log on the terminal and ifenslave the devices to pbond0 instead of bond0 after the boot process has finished. But I want this to be handled automatically during reboots, so I tried assigning the bonding slaves to pbond0 as a master in the ifcfg-eth{0,1} scripts, but that doesn't work. What is causing the bond0 rename and should this renaming be considered by initscript? Is this a user error or should I file this against bugzilla? xen or initscripts? Thanks! [*] The only reference I found was a Japanese site and google's translation of it. http://translate.google.com/translate?hl=en&sl=ja&u=http://hoop.euqset.org/… -- Axel.Thimm at ATrpms.net

Simple testing results for Xen and VMX on FC5-test2.
by You, Yongkang 12 Jan '07

12 Jan '07

Hi all, I have done a simple checking for Xen and VMX on FC5-test2. Basically, I can create VMX on FC5-test2 IA32. But FC5-test2 IA32e (x86-64) doesn't provide Xen and Xen0 kernel, so didn't do Xen and VMX testing for it. Beside of testing Xen and VMX, I also found some issues about installation, which I have updated the bug #179078 as a NB. The following is the testing results only for Xen and VMX. ========================= 1. *** IA32E hasn't RPMS about Xen hypervisor and Xen0/XenU kernels. __FAIL__ 2. *** In order to boot up IA32 Xen0, I have to add pci=noacpi as the boot parameters of Xen0 kernel, or system will hang when initial PCI. I don't know if it is only related to my Machine. __FAIL__ 3. After install IA32 Xen RPMs, I can see /boot/grub/grub.conf has been changed with Xen kernels. __PASS__ 4. *** /usr/lib/xen/boot/vmxloader isn't in the RPM package, so VMX Guest couldn't be created. I suspected build system hasn't bcc, it is from DEV86 package. __FAIL__ 5. After copy a useable vmxloader to the destination, IA32 VMX Guest can be created successfully! __PASS__ 6. VMX has good network connection and Xwindows started. __PASS__ 7. XenU can be created and works well. __PASS__ 8. Couldn't get Xen Changeset by "xm info" or "xm dmesg". 9. The new kernel names of Xen/Xen0/XenU seemed a little confused. E.g. the Xen0 name is like vmlinuz-2.6.15-1.29_FC5hypervisor. I thought hypervisor is for Xen.gz. Xen0 is the Service OS. ========================== Any comments please let me know. But I will have 8 days holiday from tomorrow, so emails reply might be slow and occasional. [FYI] We are planning to do more testing for FC5-test3. Best Regards, Yongkang (Kangkang) 永康

Can I use Xen 3.0.2 Release 23 with Fc6 Test2 and PAE ?
by shobha ranganathan 29 Sep '06

29 Sep '06

Hi, I tried to compile xen 3.0.2 release 23 in Mac with Fc6 Test2. I did "make world pae=y" and "make install". "make install" gives me errors like the following. I checked in downloads website -- for FC6 Test2 , xen version is 3.0.2-23 and for Test3 it is xen-3.0.2-33.

xenguest-install.py - Error Bad file descriptor in FC6 Test2 DomU and Dom0
by shobha ranganathan 29 Sep '06

29 Sep '06

I have a Fedora COre 6 Test 2 dom0 built from xen-3.0.2 sources. That was succssful and "xm list "worked . I did not build a domU kernel though. I am trying to install FC6 Test2 as guest Os. I setup an http server in the same machine to grab the images of Fc6 TEst2 from a directory. When I did xenguest-install.py, I get this error. Please let me know what am I missing here. 1. Have I not setup my disks correctly ? 2. Is my http daemon configuration causing problems ?

Recurring Zombie (XenU used as a web server)
by Gregor Pirnaver 27 Sep '06

27 Sep '06

For some weeks I have a problem with XenU domain used as web server. It is turning into Zombie domain: # xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 641 4 r----- 263.6 Zombie-wwwmain 2 512 1 ----cd 5238.4 dns 4 128 1 -b---- 20.1 intranet 6 512 1 -b---- 18.7 ldap 5 128 1 -b---- 61.4 mail 3 512 1 r----- 1078.0 www 1 512 1 -b---- 117.7 wwwextra 7 512 1 -b---- 33.2 (Both Xen0 and XenU are running FC5 with kernel 2.6.17-1.2174.) - How can I find out what is causing this problem? - How can I fix it / work around it / report a bug? This is production machine so I would appriciate any pointers. I didn't have this problem before. Maybe new kernel is causing the problem? Is there a way to get older versions of kernel packages? I would also like to note that when this happens networking doesn't work in ANY XenU domain. E.g.: # xm console dns after login trying to ping Google IP: # ping 72.14.221.104 PING 72.14.221.104 (72.14.221.104) 56(84) bytes of data. ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ... and when I run "init 0" in XenU (e.g. in dns XenU): # init 0 it hangs at this step: "Removing module iptables: " When I try to shutdown XenU from Xen0 it also turns to Zombie. E.g. (dns XenU domain turns into Zombie-dns): # xm shutdown dns What can I do? ____________________ http://www.email.si/

what do you recommend for cluster fs ??
by Anand Gupta 27 Sep '06

27 Sep '06

I was wondering what people use / recommend for a cluster fs for use with xen ? Also with this cluster fs, will the domU's be using flat files / lvm ? (it should be the former as per my guess since these flat files will be stored on the cluster fs, but then won't performance hit will be there for these domU's ? ) I don't want to invest in a san/ nas solution, just looking for cost effective. Right now i have a single server which i will use for the cluster fs and slowly add more servers to the cluster as and when i need more space. Atleast thats what i have thought till now. All ideas are welcome. -- regards, Anand Gupta

rpmbuild environment issues for xen guest?
by Joe Orton 27 Sep '06

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208059 This report has an x86_64 Xen guest where _libdir is expanding to /usr/lib; perhaps /etc/rpm/platform needs to be set up by the Xen guest-creating scripts? Is this a known issue? Paul, if you do: echo x86_64-redhat-linux > /etc/rpm/platform does that fix the problem? joe

"Import Error:No module named libvirt" while running xenguest-install.py in Fc5 x86 mode
by shobha ranganathan 27 Sep '06

27 Sep '06

I download xen3.0.2-23.src.rpm and build the dom0 Kernel in Fedora COre 5 in x86 mode. I did not build a domU kernel at all. I tried to run ./xenguest-install.py in dom0 kernel after booting into it.. I got this error "No module named libvirt". I then tried installing libvirt-0.0.6-1.i386.rpm using "rpm --install libvirt-0.0.6-1.i386.rpm" I get failed dependencies error such as "libxenstore.so is needed by libvirt-0.0.6-1.i386 xen is needed by libvirt-0.0.6-1.i386" what am I missing here ? I have libxenstore.so in /usr/lib. Commands like "xm list" works in dom0 kernel thanks for your help Shobha --------------------------------- Do you Yahoo!? Get on board.

%{_libdir} wrong on x86_64 xenU on FC5 from xenguest-install.py
by Paul Wouters 26 Sep '06

On Tue, 26 Sep 2006, Paul Wouters wrote: An update on this. It is not apache specific. It seems the stock FC5 xenguest-install.py on x86_64, despite running the proper 64bit kernel/userland, is somehow using /usr/lib as %{_libdir}. This is odd, as it is a virgin xenguest install from a x86_86 xen0, where the xen0 properly expands %{_libdir} to /usr/lib64, but the installed xenU does not.
