Hello, I have a server that has 5 VM now I started virt-install to install another VM, right after that all the VM lost their network connections. Also the installation of the new VM seems to hang. What is causing this and can I fix this somehow? I am using CentOS 5.2 with the repo packages: xm info host : devmaster-1 release : 2.6.18-92.1.6.el5xen version : #1 SMP Wed Jun 25 14:13:10 EDT 2008 machine : x86_64 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 3000 hw_caps : bfebfbff:20000800:00000000:00000140:0004e3bd:00000000:00000001 total_memory : 16382 free_memory : 0 node_to_cpu : node0:0-3 xen_major : 3 xen_minor : 1 xen_extra : .2-92.1.6.el5 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable cc_compiler : gcc version 4.1.2 20071124 (Red Hat 4.1.2-42) cc_compile_by : mockbuild cc_compile_domain : centos.org cc_compile_date : Wed Jun 25 13:39:56 EDT 2008 xend_config_format : 2 thank for your assistance.

Re: [Xen-users] is there a maximum of domu? my network died
Hi, you should check your current maximum of loop devices available for your domU. Besides this, there''s virtually no limit for domU''s. (I''ve seen Servers with about 40 domU''s running smoothly :) Heiko schrieb:> Hello, > > I have a server that has 5 VM now I started virt-install to install > another VM, right after that > all the VM lost their network connections. > Also the installation of the new VM seems to hang. > > What is causing this and can I fix this somehow? > > I am using CentOS 5.2 with the repo packages: > > xm info > host : devmaster-1 > release : 2.6.18-92.1.6.el5xen > version : #1 SMP Wed Jun 25 14:13:10 EDT 2008 > machine : x86_64 > nr_cpus : 4 > nr_nodes : 1 > sockets_per_node : 2 > cores_per_socket : 2 > threads_per_core : 1 > cpu_mhz : 3000 > hw_caps : > bfebfbff:20000800:00000000:00000140:0004e3bd:00000000:00000001 > total_memory : 16382 > free_memory : 0 > node_to_cpu : node0:0-3 > xen_major : 3 > xen_minor : 1 > xen_extra : .2-92.1.6.el5 > xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 > hvm-3.0-x86_32p hvm-3.0-x86_64 > xen_pagesize : 4096 > platform_params : virt_start=0xffff800000000000 > xen_changeset : unavailable > cc_compiler : gcc version 4.1.2 20071124 (Red Hat 4.1.2-42) > cc_compile_by : mockbuild > cc_compile_domain : centos.org > cc_compile_date : Wed Jun 25 13:39:56 EDT 2008 > xend_config_format : 2 > > > thank for your assistance. > > > Rupertt > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users-- Stephan Seitz Senior System Administrator *netz-haut* e.K. multimediale kommunikation zweierweg 22 97074 würzburg fon: +49 931 2876247 fax: +49 931 2876248 web: www.netz-haut.de <http://www.netz-haut.de/> registriergericht: amtsgericht würzburg, hra 5054 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
